Subject[ 05/11] floppy: do put_disk on current dr if blk_init_queue fails
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Herton Ronaldo Krzesinski <herton.krzesinski@canonical.com>

commit 238ab78469c6ab7845b43d5061cd3c92331b2452 upstream.

If blk_init_queue fails, we do not call put_disk on the current dr
(dr is decremented first in the error handling loop).
