If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e9123250c169b1faf33ee84e3991de7f9196b7bc Author: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Date: Sat Apr 30 12:33:18 2022 -0700 ALSA: hda - fix unused Realtek function when PM is not enabled [ Upstream commit c3d9ca93f1e3bd3d1adfc4479a12c82fed424c87 ] 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.
