From: Johannes Berg Date: Wed, 17 Feb 2010 12:54:08 +0000 (-0800) Subject: iwlwifi: remove STATUS_MODE_PENDING X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b55e75ed926ded110293b0d1e24eb6a878883115;p=linux-beck.git iwlwifi: remove STATUS_MODE_PENDING Since rfkill integration, mac80211 can no longer add an interface while the hardware is not ready, so STATUS_MODE_PENDING can never be set. Also, remove another superfluous channel sanity check and return the commit_rxon return value in case it failed.
