Subject: ath9k & ath9k_htc: move ath_rx_stats to cmn
X-Git-Tag: omap-for-v3.16/fixes-against-rc1~36^2~122^2^2~62
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b5a0c86a56e4494eab84b142ab5501eb62685150;p=pandora-kernel.git

ath9k & ath9k_htc: move ath_rx_stats to cmn

and use it. This move need changes in both drivers.
