During the review of the patches from unm.edu, one of the patterns
I noticed is the amount of patches trying to fix pm_runtime_get_sync()
calls.
After analyzing the feedback from version 1 of this series, I noticed
a few other weird behaviors at the PM runtime resume code. So, this
series start addressing some bugs and issues at the current code.
Then, it gets rid of pm_runtime_get_sync() at the media subsystem
(with 2 exceptions).
It should be noticed that
Commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
added a new method to does a pm_runtime get, which increments
the usage count only on success.
The rationale of getting rid of pm_runtime_get_sync() is:
1. despite its name, this is actually a PM runtime resume call,
but some developers didn't seem to realize that, as I got this
pattern on some drivers:
pm_runtime_get_sync(&client->dev);
pm_runtime_disable(&client->dev);
pm_runtime_set_suspended(&client->dev);
pm_runtime_put_noidle(&client->dev);
It makes no sense to resume PM just to suspend it again ;-)
2. Usual *_get() methods only increment their use count on success,
but pm_runtime_get_sync() increments it unconditionally. Due to
that, several drivers were mistakenly not calling
pm_runtime_put_noidle() when it fails;
3. The name of the new variant is a lot clearer:
pm_runtime_resume_and_get()
As its same clearly says that this is a PM runtime resume function,
that also increments the usage counter on success;
4. Consistency: we did similar changes subsystem wide with
for instance strlcpy() and strcpy() that got replaced by
strscpy(). Having all drivers using the same known-to-be-safe
methods is a good thing;
5. Prevent newer drivers to copy-and-paste a code that it would
be easier to break if they don't truly understand what's behind
the scenes.
This series replace places pm_runtime_get_sync(), by calling
pm_runtime_resume_and_get() instead.
This should help to avoid future mistakes like that, as people
tend to use the existing drivers as examples for newer ones.
compile-tested only.
Patches 1 to 7 fix some issues that already exists at the current
PM runtime code;
patches 8 to 20 fix some usage_count problems that still exists
at the media subsystem;
patches 21 to 78 repaces pm_runtime_get_sync() by
pm_runtime_resume_and_get();
Patch 79 (and a hunk on patch 78) documents the two exceptions
where pm_runtime_get_sync() will still be used for now.

The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
Replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter and avoid memory
leaks.
While here, fix the return contition of mtk_mdp_m2m_start_streaming(),
as it doesn't make any sense to return 0 if the PM runtime failed
to resume.

Commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
added pm_runtime_resume_and_get() in order to automatically handle
dev->power.usage_count decrement on errors.
Use the new API, in order to cleanup the error check logic.
