3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eliad Peller <el...@wizery.com>
commit 8c26d458394be44e135d1c6bd4557e1c4e1a0535 upstream.
tsc can be NULL (mac80211 currently always passes NULL),
resulting in NULL-dereference. check before copying it.
