From: Bill Jordan Date: Wed, 31 Aug 2011 21:51:00 +0000 (-0400) Subject: ath9k: ath9k_hw_set_txpowerlimit sets previous txpower X-Git-Tag: v3.2-rc1~129^2~254^2~81 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f84f234c6417e3d60b1cfeaf9d16c3bd1c8fe2a5;p=pandora-kernel.git ath9k: ath9k_hw_set_txpowerlimit sets previous txpower In commit 9c204b46c7af93e334114bea1f5eeaa6fea9ba07 (ath9k_hw: do not limit initial tx power to 20 dbm), setting of txpower was broken. This patch fixes it by initializing reg_pwr from the new power limit, not the previous value. Signed-off-by: Bill Jordan Signed-off-by: John W.
