Subject: [PATCH 2/3] ath9k: Fix ATH9K_HW_CAP_HT usage
Date: Mon,  4 Feb 2013 15:38:23 +0530	[thread overview]
Message-ID: <1359972504-8900-2-git-send-email-sujith@msujith.org> (raw)
In-Reply-To: <1359972504-8900-1-git-send-email-sujith@msujith.org>

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

There are a few places where the station's HT capabilities
should be checked instead of ATH9K_HW_CAP_HT, which is a global
feature for the driver. Fix this.
