From bec7760a6c5fa59593dac264fa0c628e46815986 Mon Sep 17 00:00:00 2001 From: Gergo Koteles Date: Fri, 8 Mar 2024 18:41:42 +0100 Subject: [PATCH] ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend The amplifier doesn't loose register state in software shutdown mode, so there is no need to reset the cur_* values. Without these resets, the amplifier can be turned on after runtime_suspend without waiting for the program and profile to be restored.
