[PATCH v3 30/79] media: i2c: dw9714: use pm_runtime_resume_and_get()

From: Mauro Carvalho Chehab
Date: Tue Apr 27 2021 - 06:28:38 EST


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.
