From: Bruno Randolf Date: Mon, 7 Jun 2010 04:11:35 +0000 (+0900) Subject: ath5k: no need to save/restore the default antenna X-Git-Tag: v2.6.36-rc1~571^2~107^2~305 X-Git-Url: http://git.samba.org/samba.git/?a=commitdiff_plain;h=20fbed21e934355ee00850f6dead22be3147893f;p=sfrench%2Fcifs-2.6.git ath5k: no need to save/restore the default antenna Since ath5k_hw_set_antenna_mode() always writes the default antenna register and is called at the end of reset, there is no need to separately save and restore the default antenna.
