The patch titled
forcedeth: fix "fix multi irq issues"
has been removed from the -mm tree. Its filename is
forcedeth-fix-fix-multi-irq-issues.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
------------------------------------------------------
Subject: forcedeth: fix "fix multi irq issues"
From: Manfred Spraul <manfred@xxxxxxxxxxxxxxxx>
Fix bug introduced by ebf34c9b6fcd22338ef764b039b3ac55ed0e297b, covered in
http://bugzilla.kernel.org/show_bug.cgi?id=6568.
Remove second instance of the request_irq() calls: they were moved from
nv_open into nv_request_irq.
Thanks to Alistair Strachan <alistair@xxxxxxxxxxxxx> for reporting and
persisting.
