[PATCH v2 20/26] drm: tegra: Remove #ifdef guards for PM related functions
From: Paul Cercueil
Date: Tue Nov 29 2022 - 14:23:38 EST
Use the RUNTIME_PM_OPS() and pm_ptr() macros to handle the
.runtime_suspend/.runtime_resume callbacks.
These macros allow the suspend and resume 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.
