Subject: [PATCH 2/4] fs: devfs: Allow mount path in cdev_open
Date: Tue, 13 Oct 2015 09:51:52 +0200	[thread overview]
Message-ID: <1444722714-30445-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1444722714-30445-1-git-send-email-s.hauer@pengutronix.de>

When opening a cdev also allow a path beginning with /dev/ as some
users of cdev_open already open coded this behaviour.
