Since the SIMPLE_DEV_PM_OPS macro and the pm pointer are anyway
defined when CONFIG_PM_SLEEP is not set, remove the ifdef for it
and indicate that the mtk_hdmi_{remove,suspend} functions may be
unused (as they are, in case PM support is not built-in).
I see many driver use CONFIG_PM_SLEEP,
and SIMPLE_DEV_PM_OPS() is defined to support suspend/resume function is not exist when CONFIG_PM_SLEEP is not defined,
so there is no strong purpose to apply this patch.
While at it, to improve readability, also compress the
SIMPLE_DEV_PM_OPS declaration as it even fits in less
than 80 columns.
You have many typesetting in some patches.
But I think typesetting is not related to the main purpose of that patch.
I would like you to gather these typesetting modification to a readability patch.
It's a cleanup per-se, and I think that pushing a commit for one line would be
cluttering the commit history way too much... and it's the same for the other
drivers anyway.
Also, backporting (if needed) is easier when those very small changes are in
tandem with the actual bigger change.
Cheers,
Angelo
