Subject: [PATCH 4.4 42/56] padata: free correct variable

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

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

From: Jason A. Donenfeld <Jason@...c4.com>

commit 07a77929ba672d93642a56dc2255dd21e6e2290b upstream.

The author meant to free the variable that was just allocated, instead
of the one that failed to be allocated, but made a simple typo. This
patch rectifies that.
