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.
While there's nothing wrong with the current usage on this driver, as we're getting rid of the pm_runtime_get_sync() call all over the media subsystem, let's remove the last occurrence on this driver.
