ALSA: hda/sigmatel: Fix unused variable warning for beep power change

tiwai · tiwai · commit 51bdc8bb8252 · 2022-09-05T15:07:07.000+02:00
The newly added stac_check_power_status() caused a compile warning when CONFIG_SND_HDA_INPUT_BEEP is disabled. Fix it. Fixes: 414d38b ("ALSA: hda/sigmatel: Keep power up while beep is enabled") Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/r/20220905130630.2845-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
