From f5c38ef06e005705ef87b7a77752c183bacb94cc Mon Sep 17 00:00:00 2001 From: Sujith Date: Mon, 30 Mar 2009 15:28:57 +0530 Subject: [PATCH] ath9k: Fix bug in determining HT40 mode This patch fixes a bug in checking for HT40 mode. The STA's mode can be determined from the cached HT capabilities, use that and remove the redundant variable 'rc_phy_mode'. Signed-off-by: Sujith Signed-off-by: John W.
