From: Michal Kazior Date: Tue, 21 Oct 2014 07:10:29 +0000 (+0300) Subject: ath10k: clean up assoc code X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=590922a824cd9c16b3f43c59e4defd411a3be5dc;p=openwrt%2Fstaging%2Fblogic.git ath10k: clean up assoc code There's no need to pass bss_conf explicitly as it is accessible via vif pointer. This requires slight changes in function prototypes. While at it clean up listen interval workaround/command.
