Merge tag 'mac80211-for-davem-2015-01-06' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Here's just a single fix - a revert of a patch that broke the p54 and cw2100 drivers (arguably due to bad assumptions there.) Since this affects kernels since 3.17, I decided to revert for now and we'll revisit this optimisation properly for -next. Signed-off-by: David S. Miller <davem@davemloft.net>
