From 22db998afdddcbf65eb5385f05a2fec7c2959a1e Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Mon, 2 Jan 2023 18:17:48 +0000 Subject: [PATCH] Input: pcfg8574_keypad - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the #ifdef guards.
