Subject: [PATCH 3.16 087/132] platform/x86: alienware-wmi: printing the
 wrong error code

3.16.74-rc1 review patch.  If anyone has any objections, please let me know.

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

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

commit 6d1f8b3d75419a8659ac916a1e9543bb3513a882 upstream.

The "out_data" variable is uninitialized at the point.  Originally, this
used to print "status" instead and that seems like the correct thing to
print.
