From: Johannes Berg Date: Mon, 5 Mar 2012 19:24:23 +0000 (-0800) Subject: iwlwifi: build some station commands directly X-Git-Tag: v3.4-rc1~177^2~108^2~141 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9451ca1a31be44f8235c3f8f998ff27fc7a8395e;p=profile%2Fivi%2Fkernel-x86-ivi.git iwlwifi: build some station commands directly In the powersave related functions we only need to set a few parameters for the station command and can otherwise leave it blank -- there's no need to copy it from the database. This allows us to not use the sta lock here. Signed-off-by: Johannes Berg Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
