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.
On contrary of the common sense that a foo_get() function will
only increment the usage on success, pm_runtime_get_sync()
increments it unconditionally.
Due to that, there are bugs on lots of places, that ended being
gradually fixed, but, still there are a few places on media where
this is still broken.
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.
This series replace all places where the old pm_runtime_get_sync()
is called, using 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.
