Subject: [patch] vlynq: fix another resource size off by 1 error

We fixed the call to request_mem_region() patch
3354f73 ('drivers/vlynq/vlynq.c: fix resource size off by 1 error').
But we need to fix the call the release_mem_region() as well.

Sorry for this late answer, vlynq changes usually go through AKPM's tree as I
don't maintain one due to the low number of changes in this code.

Resending (again) with Andrew's email corrected.

Hi, Andrew, Florian says this has to go through your tree. I assume
