Subject: [PATCH] Fix infinite loop on dev_mc_unsync()
Date: Fri, 9 Nov 2007 10:11:35 -0500	[thread overview]
Message-ID: <20071109151135.GA12982@pogo> (raw)

While reviewing net/core/dev_mcast.c I found what I think is an 
infinite loop on dev_mc_unsync(). This fixes it. We make use of
this guy on mac80211 in ieee80211_stop(). This is untested.
