From cbdcefbde882c156b29b48dc76ab2738b9ceb2fc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 7 Feb 2024 16:51:30 +0100 Subject: [PATCH] ALSA: cs4281: Simplify with DEFINE_SIMPLE_DEV_PM_OPS() Use the new DEFINE_SIMPLE_DEV_PM_OPS() instead of SIMPLE_DEV_PM_OPS() for code-simplification. We need no longer CONFIG_PM_SLEEP ifdefs. This ends up with the allocation of a few additional bytes for the register dumps even if it's not really used, but the code simplification should justify the cost.
