From ce37ab42ad8b38ef2f36c31c6b4c39b87f36b792 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 3 Dec 2007 12:46:12 +0000 Subject: [PATCH] [MTD] Always initialise mutex in new mtd_blktrans_dev. We were only initialising the mutex in the case where the new device was automatically allocated the highest minor number. If the caller specified a minor number, or if it filled in a free slot which was made by a previous device deregistering, the mutex wouldn't get initialised when we jumped out of the loop.
