Subject: [PATCH v2 62/79] media: exynos4-is: use pm_runtime_resume_and_get()
Date: Tue, 27 Apr 2021 12:13:29 +0200	[thread overview]
Message-ID: <549d4b739a70d1b273590693a14cf9c0efefa8c1.1619518193.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1619518193.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.
