From 53d36818ae56bc284eb0b64664c55e018bca561f Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Tue, 29 Nov 2022 19:19:32 +0000 Subject: [PATCH] drm: panfrost: Remove #ifdef guards for PM related functions Use the EXPORT_GPL_RUNTIME_DEV_PM_OPS() and pm_ptr() macros to handle the PM callbacks. These macros allow the PM functions to be automatically dropped by the compiler when CONFIG_PM is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.
