Subject: [PATCH 06/11] media: saa7134: fix saa7134_initdev error handling logic
Date: Wed, 16 Jun 2021 14:28:32 +0200	[thread overview]
Message-ID: <9e1b48aeaf261e37aa99d868c44acfe7df0d7fc4.1623846327.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1623846327.git.mchehab+huawei@kernel.org>

Smatch reported an issue there:
	drivers/media/pci/saa7134/saa7134-core.c:1302 saa7134_initdev() warn: '&dev->devlist' not removed from list

But besides freeing the list, the media controller graph also
needs to be cleaned up on errors. Address those issues.
