Subject: [PATCH 00/26] drm: Get rid of #ifdef CONFIG_PM* guards
Hi,
This patchset updates the DRM drivers to use the new set of PM-related
macros introduced recently.
The point of these macros is to allow the PM functions to be
automatically dropped by the compiler when CONFIG_PM or CONFIG_SUSPEND
is disabled, without having to use #ifdef guards.
This has the advantages of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
Note that some drivers (etnaviv, tegra, vc4) currently don't have any
.suspend/.resume callbacks, but do provide
.runtime_suspend/.runtime_resume callbacks. These drivers should most
likely use DEFINE_RUNTIME_DEV_PM_OPS(), which provides .suspend/.resume
callbacks as well (pm_runtime_force_suspend / pm_runtime_force_resume
respectively). I did not do that, because that would be a functional
change and the callbacks being missing may actually be on purpose.
Checkpatch complains about patch [11/26], as I replaced a
"#if defined(IS_NOT_BROKEN)" to a "if (IS_ENABLED(IS_NOT_BROKEN))".
I don't really know how to make it better so I left it like that.
Compile-tested with allyesconfig, with the following cases:
- CONFIG_PM=y CONFIG_PM_SLEEP=y
- CONFIG_PM=y CONFIG_PM_SLEEP=n
- CONFIG_PM=n
Cheers,
-Paul
