Merge tag 'mmc-v4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson: "Here are some mmc fixes intended for v4.9 rc2. This time I have also included a few changes for a memstick driver which has a corresponding mmc driver. They use the same USB device as parent, hence both needs to play nice with runtime PM, which they didn't. MMC core: - Update MAINTAINERS as the mmc tree moved to kernel.org - A few fixes for HS400es mode - A few other minor fixes MMC host: - sdhci: Fix an issue when dealing with stop commands - sdhci-pci: Fix a bus power failure issue - sdhci-esdhc-imx: Correct two register accesses - sdhci-of-arasan: Fix the 1.8V I/O signal switch behaviour - rtsx_usb_sdmmc: Fix runtime PM issues Other: (Because of no maintainer) - memstick: rtsx_usb_ms: Fix runtime PM issues" * tag 'mmc-v4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: MAINTAINERS: mmc: Move the mmc tree to kernel.org memstick: rtsx_usb_ms: Manage runtime PM when accessing the device memstick: rtsx_usb_ms: Runtime resume the device when polling for cards mmc: rtsx_usb_sdmmc: Handle runtime PM while changing the led mmc: rtsx_usb_sdmmc: Avoid keeping the device runtime resumed when unused mmc: sdhci: cast unsigned int to unsigned long long to avoid unexpeted error mmc: sdhci-esdhc-imx: Correct two register accesses mmc: sdhci-pci: Fix bus power failing to enable for some Intel controllers mmc: sdhci-pci: Let devices define their own sdhci_ops mmc: sdhci: Rename sdhci_set_power() to sdhci_set_power_noreg() mmc: sdhci: Fix SDHCI_QUIRK2_STOP_WITH_TC mmc: core: Annotate cmd_hdr as __le32 mmc: sdhci-of-arasan: add sdhci_arasan_voltage_switch for arasan, 5.1 mmc: core: changes frequency to hs_max_dtr when selecting hs400es mmc: core: switch to 1V8 or 1V2 for hs400es mode mmc: block: add missing header dependencies mmc: sdhci-of-arasan: Fix non static symbol warning
