Subject: [PATCH v2 01/79] media: venus: fix PM runtime logic at venus_sys_error_handler()
Date: Tue, 27 Apr 2021 12:12:28 +0200	[thread overview]
Message-ID: <d20ddc17711e66db4b7c30ee3ccb27c7d90a9f43.1619518193.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1619518193.git.mchehab+huawei@kernel.org>

The venus_sys_error_handler() assumes that pm_runtime was
able to resume, as it does things like:

	while (pm_runtime_active(core->dev_dec) || pm_runtime_active(core->dev_enc))
		msleep(10);

Well, if, for whatever reason, this won't happen, the routine
won't do what's expected. So, check for the returned error
condition, warning if it returns an error.

Fixes: af2c3834c8ca ("[media] media: venus: adding core part and helper functions")
