[PATCH 28/78] media: i2c: dw9807-vcm: use pm_runtime_resume_and_get()

From: Mauro Carvalho Chehab
Date: Sat Apr 24 2021 - 02:48:48 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.
