ALSA: hda/tegra: avoid build error without CONFIG_PM
The #ifdef protection around the PM functions is wrong, leading to a failed reference in some configurations: sound/pci/hda/hda_tegra.c: In function 'hda_tegra_runtime_suspend': sound/pci/hda/hda_tegra.c:273:2: error: implicit declaration of function 'hda_tegra_disable_clocks'; did you mean 'hda_tegra_enable_clocks'? [-Werror=implicit-function-declaration] Better remove the #ifdefs entirely and rely on the compiler silently dropping unused functions marked __maybe_unused. Fixes: 707e0759f2f4 ("ALSA: hda/tegra: implement runtime suspend/resume") Acked-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
