Subject: media: sunxi: use pm_runtime_resume_and_get()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=79e790ff0bc5192f874cc587c462825556133d1c;p=linux.git

media: sunxi: use pm_runtime_resume_and_get()

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.
