Subject: [PATCH 3.13.y-ckt 43/86] can: Use correct type in sizeof() in nla_put()

3.13.11-ckt31 -stable review patch.  If anyone has any objections, please let me know.

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

From: Marek Vasut <marex@...x.de>

commit 562b103a21974c2f9cd67514d110f918bb3e1796 upstream.

The sizeof() is invoked on an incorrect variable, likely due to some
copy-paste error, and this might result in memory corruption. Fix this.
