Subject: [PATCH v5 01/25] staging: media: imx7-mipi-csis: use pm_runtime_resume_and_get()
Date: Thu, 6 May 2021 17:25:39 +0200 [thread overview]
Message-ID: <74ab04a6bb8949d9b12b203def1e0c57b7793db5.1620314616.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.
