Subject: Re: [PATCH 2.6.20 2/2] ehca: ehca_irq.c: fix mismatched spin_unlock in irq handler

hmm, code line too long. please ignore the previous patch. here is the one
with correct length of code line.
Thanks
Nam


This is a patch for ehca_irq.c that fixes an unproper use of spin_unlock
in irq handler.
