Subject: [222/272] net: clear heap allocation for ethtool_get_regs()

2.6.37-stable review patch.  If anyone has any objections, please let us know.

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

From: Eugene Teo <eugeneteo@...nel.org>

commit b7c7d01aaed1f71d9afe815a569f0a81465a1744 upstream.

There is a conflict between commit b00916b1 and a77f5db3. This patch resolves
the conflict by clearing the heap allocation in ethtool_get_regs().
