[49/90] b44: Fix wedge when using netconsole.
From: Greg KH
Date: Wed Dec 16 2009 - 20:36:08 EST
2.6.31-stable review patch. If anyone has any objections, please let us know.
------------------
From: David S. Miller <davem@xxxxxxxxxxxxx>
[ Upstream commit 0cae200eec6330cd2c20b24279597be1da50dc93 ]
Fixes kernel bugzilla #14691
Due to the way netpoll works, it is perfectly legal to see
NAPI already scheduled when new device events are pending
in b44_interrupt().
So logging a message about it is wrong and in fact harmful.
Based upon a patch by Andreas Mohr.
