From cbd1db4bb30ca684d811f4b5bf5dc099aa582445 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 27 Jul 2011 15:01:02 +0200 Subject: [PATCH] ath9k: initialize tx chainmask before testing channel tx power values commit c1227340ca65c2069222a956a68b6842d460c4f4 upstream. With an uninitialized chainmask, the per-channel power will only contain the power limits for a single chain instead of the combined tx power. Signed-off-by: Felix Fietkau Signed-off-by: John W.
