From: Emmanuel Grumbach Date: Fri, 29 Mar 2013 11:52:17 +0000 (+0300) Subject: iwlwifi: mvm: beautify code in BT Coex X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9e511c3135ae4937d5cfd6a109c2f7c22e111f65;p=openwrt%2Fstaging%2Fblogic.git iwlwifi: mvm: beautify code in BT Coex The iterators don't need to know what bt_kill_msk means. All they need to know is if reduced Tx power is enabled on an interface or not. So change the member of the iterator to be a bool.
