3.2.102-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg johannes.berg@intel.com
commit 657308f73e674e86b60509a430a46e569bf02846 upstream.
Similar to the ancient commit a5fe8e7695dc ("regulatory: add NUL to alpha2"), add another byte to alpha2 in the request struct so that when we use nla_put_string(), we don't overrun anything.
