From 68c341c888f448410de027ca4b3d113f2b437c54 Mon Sep 17 00:00:00 2001 From: Raphael Gallais-Pou Date: Tue, 16 Jul 2024 20:00:10 +0200 Subject: [PATCH] serial: st-asc: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based kernel configuration guards.
