git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat shows we've had again a lot of works done for this cycle: the majority of changes are the continued componentization and code refactoring in ASoC, the tree-wide PCM API updates and cleanups and SOF updates while a few ASoC driver updates are seen, too. Here we go, some highlights: Core: - Finally y2038 support landed to ALSA ABI; some ioctls have been extended and lots of tricks were applied - Applying the new managed PCM buffer API to all drivers; the API itself was already merged in 5.5 - The already deprecated dimension support in ALSA control API is dropped completely now - Verification of ALSA control elements to catch API misuses ASoC: - Further code refactorings and moving things to the component level - Lots of updates and improvements on SOF / Intel drivers; now including common HDMI driver and SoundWire support - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308 HD-audio: - Improved ring-buffer communications using waitqueue - Drop the superfluous buffer preallocation on x86 Others: - Many code cleanups, mostly constifications over the whole tree - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix - FireWire: code refactoring for oxfw and dice drivers" * tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (638 commits) ALSA: usb-audio: add quirks for Line6 Helix devices fw>=2.82 ALSA: hda: Add Clevo W65_67SB the power_save blacklist ASoC: soc-core: remove null_snd_soc_ops ASoC: soc-pcm: add soc_rtd_trigger() ASoC: soc-pcm: add soc_rtd_hw_free() ASoC: soc-pcm: add soc_rtd_hw_params() ASoC: soc-pcm: add soc_rtd_prepare() ASoC: soc-pcm: add soc_rtd_shutdown() ASoC: soc-pcm: add soc_rtd_startup() ASoC: rt1015: add rt1015 amplifier driver ASoC: madera: Correct some kernel doc ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order ASoC: Intel: skl_hda_dsp_common: Fix global-out-of-bounds bug ASoC: madera: Correct DMIC only input hook ups ALSA: cs46xx: fix spelling mistake "to" -> "too" ALSA: hda - Add docking station support for Lenovo Thinkpad T420s ASoC: Add MediaTek MT6660 Speaker Amp Driver ASoC: dt-bindings: rt5645: add suppliers ASoC: max98090: fix deadlock in max98090_dapm_put_enum_double() ASoC: dapm: add snd_soc_dapm_put_enum_double_locked ...

2018-06-12treewide: Use array_size() in vmalloc()Kees Cook
The vmalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vmalloc(a * b) with: vmalloc(array_size(a, b)) as well as handling cases of: vmalloc(a * b * c) with: vmalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vmalloc(4 * 1024) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( vmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | vmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( vmalloc( - sizeof(u8) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(__u8) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(char) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(u8) * COUNT + COUNT , ...) | vmalloc( - sizeof(__u8) * COUNT + COUNT , ...) | vmalloc( - sizeof(char) * COUNT + COUNT , ...) | vmalloc( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( vmalloc( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vmalloc( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ vmalloc( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( vmalloc( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( vmalloc( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vmalloc( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vmalloc( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( vmalloc( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( vmalloc(C1 * C2 * C3, ...) | vmalloc( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( vmalloc(C1 * C2, ...) | vmalloc( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc().

2017-01-26ALSA: cs46xx: constify snd_pcm_ops structuresBhumika Goyal
Declare snd_pcm_ops structures as const as they are either stored in the ops field of a snd_pcm_substream structure or passed as an argument to the function snd_pcm_set_ops. The function argument and the ops field are of type const, so snd_pcm_ops structures having this property can be made const too.

2015-10-30ALSA: cs46xx: Fix suspend for all channelsOndrej Zary
snd_cs46xx_suspend() is missing snd_pcm_suspend_all calls for pcm_rear, pcm_center_lfe and pcm_iec958. There's also a copy/paste bug in snd_cs46xx_pcm_iec958(), overwriting pcm_rear in struct snd_cs46xx, leaving pcm_iec958 unused. Fix all this to allow all channels to survive suspend/resume.

Currently, the Duplicate front control is enabled only for two specific revisions of CS4294. Enable it for all CS4294 and CS4298 codecs instead.

2015-01-09ALSA: cs46xx: Simplify PM callbacksTakashi Iwai
This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801: PCI core handles power state for us]. Since pci_set_power_state(), pci_save_state() and pci_restore_state() are already done in the PCI core side, so we don't need to it doubly. Also, pci_enable_device(), pci_disable_device() and pci_set_master() calls in PM callbacks are superfluous nowadays, too, so get rid of them as well. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-04ALSA: Deletion of checks before the function call "iounmap"Markus Elfring
The iounmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-02ALSA: cs46xx: Remove always NULL parametersLars-Peter Clausen
The various PCM and MIDI allocation functions in this driver take a pointer to a pointer of a PCM/MIDI object where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit shorter and cleaner. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2013-05-29ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at removeTakashi Iwai
As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>
