From f84f234c6417e3d60b1cfeaf9d16c3bd1c8fe2a5 Mon Sep 17 00:00:00 2001 From: Bill Jordan Date: Wed, 31 Aug 2011 17:51:00 -0400 Subject: [PATCH] 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.
