Subject: [PATCH v4 23/79] staging: media: ipu3: use pm_runtime_resume_and_get()
Date: Wed, 28 Apr 2021 16:51:44 +0200	[thread overview]
Message-ID: <ab2332b27d0043574a72a42ec8d757fd06279cc6.1619621413.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1619621413.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.
