Merge tag 'iwlwifi-next-for-kalle-2015-09-21' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

* some debugfs improvements;
* fix signedness in beacon statistics;
* deinline some functions to reduce size when device tracing is enabled;
* filter beacons out in AP mode when no stations are associated;
* deprecate firmwares version -12;
* fix a runtime PM vs. legacy suspend race;
* one-liner fix for a ToF bug;
* clean-ups in the rx code;
* small debugging improvement;
* fix WoWLAN with new firmware versions;
