John W. Linville says:

====================
pull request: wireless-next 2014-10-09

Please pull this batch of fixes intended for the 3.18 stream!

Andrea Merello makes rtl818x_pci use a more reasonable transmission
rate for HW generated frames.

Fabian Frederick tweaks some kernel-doc bits to avoid warnings.

Larry Finger corrects a possible unaligned access in the rtlwifi code.

Marek Puzyniak avoids a kernel panic in ath9k_hw_reset.

Sujith Manoharan goes for the hat trick -- he fixes a smatch warning
in the shared ath code, he fixes a crash in ath9k, and he corrects
a sequence number assignment problem in ath9k too.

For ease of merging, I pulled the last bits of the wireless tree as well...

Please let me know if there are problems!
