Subject: devfs fixes
Date: Tue, 13 Oct 2015 09:51:50 +0200	[thread overview]
Message-ID: <1444722714-30445-1-git-send-email-s.hauer@pengutronix.de> (raw)

We have some places in the code where we expect a cdev name, but
also allow a full /dev/ path. We handle this by doing:

	if (!strncmp(name, "/dev/", 5))
		name += 5;

As Peter noticed this of course only works when devfs is mounted on
/dev/. With this series we actually enforce that to avoid surprises.
Also we "officially" allow to pass a /dev/ path for opening a cdev
by moving the above code to cdev_open.
