Subject: [PATCH 20/25] media: sti/delta: use pm_runtime_resume_and_get()
Date: Wed,  5 May 2021 11:42:10 +0200	[thread overview]
Message-ID: <a2056fdad3cd3d87b5e9653dc18deca83bb554c2.1620207353.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1620207353.git.mchehab+huawei@kernel.org>

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.
