Merge tag 'iwlwifi-for-john-2014-11-03' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes
Emmanuel Grumbach <egrumbach@gmail.com> says:
"I fix here two issues that are related to the firmware
loading flow. A user reported that he couldn't load the
driver because the rfkill line was pulled up while we
were running the calibrations. This was happening while
booting the system: systemd was restoring the "disable
wifi settings" and that raised an RFKILL interrupt during
the calibration. Our driver didn't handle that properly
and this is now fixed."
