Subject: [PATCH 3.12 084/101] drivers/vlynq/vlynq.c: fix another resource size off by 1 error

From: Dan Carpenter <dan.carpenter@...cle.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 59d42cd43c7335a3a8081fd6ee54ea41b0c239be upstream.

We fixed the call to request_mem_region() in commit 3354f73b24c6
("drivers/vlynq/vlynq.c: fix resource size off by 1 error").  But we
need to fix the call the release_mem_region() as well.
