Subject: [PATCH 20/78] media: mtk-vcodec: fix pm_runtime_get_sync() usage count
Date: Sat, 24 Apr 2021 08:44:30 +0200 [thread overview]
Message-ID: <f4906ceabe4bbc6a6b10c2409a44b7a14f5c0926.1619191723.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1619191723.git.mchehab+huawei@kernel.org>
The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter and avoid memory
leaks.
