From bff03d5cab0917b7f61cee335202ace23c4c6b9e Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 30 Jan 2022 19:31:30 +0000 Subject: [PATCH] iio:proximity:as3935: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc 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 config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.
