Subject: [PATCH v5 07/25] media: rockchip/rga: use pm_runtime_resume_and_get()
Date: Thu,  6 May 2021 17:25:45 +0200
Message-ID: <ce18a4f9ca1bdcf4c68e77eaa410ec03a6ec8fe2.1620314616.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1620314616.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.
