[PATCH] ALSA: hda - fix unused Realtek function when PM is not enabled

From: Randy Dunlap
Date: Sat Apr 30 2022 - 15:33:38 EST


When CONFIG_PM is not enabled, alc_shutup() is not needed,
so move it inside the #ifdef CONFIG_PM guard.
Also drop some contiguous #endif / #ifdef CONFIG_PM for simplicity.

Fixes this build warning:
sound/pci/hda/patch_realtek.c:886:20: warning: unused function 'alc_shutup'

Fixes: 08c189f2c552 ("ALSA: hda - Use generic parser codes for Realtek driver")
