Subject: [117/151] ath9k: Fix TX hang poll routine
Date: Wed, 16 Dec 2009 19:56:54 -0800	[thread overview]
Message-ID: <20091217035658.141592007@mini.kroah.org> (raw)
In-Reply-To: <20091217040208.GA26571@kroah.com>

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------


From: Sujith <Sujith.Manoharan@atheros.com>

This is a backport of upstream commit: 332c556633b8c5fb4e890b1783122f2315526590

When TX is hung, the chip is reset. Ensure that
the chip is awake by using the PS wrappers.
