Subject: [PATCH 6/8] ath9k: Simplify checks in quick_scan
Date: Thu,  1 Aug 2013 11:53:22 +0530	[thread overview]
Message-ID: <1375338204-2021-6-git-send-email-sujith@msujith.org> (raw)
In-Reply-To: <1375338204-2021-1-git-send-email-sujith@msujith.org>

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

There is a function to do a ratio comparison for ALT,
so make use of it.
