Subject: cciss: check for msi in interrupt_not_for_us
From: Mike Miller <mike.miller@xxxxxx>
Check to see if h->msi[x]_vector is set. We need this for a following
patch. Without this check we process one interrupt then stop because in
msi[x] mode the interrupt pending bit is not set. Not sure why we didn't
encounter this before.
