Mauro Carvalho Chehab 59087b66ea media: exynos-gsc: fix pm_runtime_get_sync() usage count
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 dd8088d5a8 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter, avoiding
a potential PM usage counter leak.

As a bonus, as pm_runtime_get_sync() always return 0 on
success, the logic can be simplified.
