Subject: [PATCH 4.2 167/258] hv: util: checking the wrong variable

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

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

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

commit 9dd6a06430c94299651d74b9ed5ca8396ab8ff1f upstream.

We don't catch this allocation failure because there is a typo and we
check the wrong variable.

Fixes: 14b50f80c32d ('Drivers: hv: util: introduce hv_utils_transport abstraction')
