Subject: [RFC] ath9k correct interrupts ?
Date: Fri, 18 Feb 2011 14:00:53 +0100	[thread overview]
Message-ID: <20110218125955.GA4209@redhat.com> (raw)

I'm not sure if that patch is correct or not. It possibly fix
change from commit 4df3071ebd92ef7115b409da64d0eb405d24a631
"ath9k_hw: optimize interrupt mask changes" that looks
suspicious for me. But from other hand this patch
could be totally wrong. Felix?
