Subject: [ALSA][2/6] Fix oops when initialisation fails.
Date: Mon, 15 Mar 2004 19:27:06 GMT [thread overview]
Message-ID: <200403151927.i2FJR6KQ015688@delerium.codemonkey.org.uk> (raw)
Try modprobing a driver that the hardware doesn't exist for.
In a few situations, you'll hit an oops due to proc_id not
being filled out that early.
