3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Santosh Nayak <santoshprasadna...@gmail.com>
commit 82163edcdfa4eb3d74516cc8e9f38dd3d039b67d upstream.
There is a missing "up_write()" here. Semaphore should be released
before returning error value.
