ALSA: hda: fix unused variable warning
When CONFIG_X86=n function azx_snoop doesn't use the variable chip it only returns true. sound/pci/hda/hda_intel.c: In function ‘dma_alloc_pages’: sound/pci/hda/hda_intel.c:2002:14: warning: unused variable ‘chip’ [-Wunused-variable] struct azx *chip = bus_to_azx(bus); ^~~~ Create a inline function of azx_snoop. Fixes: a41d122449be ("ALSA: hda - Embed bus into controller object") Signed-off-by: Anders Roxell <anders.roxell@linaro.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
