Subject: staging: media: ipu3: use pm_runtime_resume_and_get()
Author:  Mauro Carvalho Chehab <[email protected]>
Date:    Fri Apr 23 17:19:22 2021 +0200

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.
