[PATCH 3/6] cciss: check for msi in interrupt_not_for_us
in [Kernel]
|
From: Mike Miller on 28 May 2010 16:00 Patch 3 of 4 cciss: check for msi in interrupt_no_for_us This patch checks 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.
