From 2cf3af1c9ec26f8db3f386e48f9d979ad8bb3eff Mon Sep 17 00:00:00 2001 From: Mike Miller Date: Wed, 2 Jun 2010 12:58:02 -0700 Subject: [PATCH] cciss: check for msi in interrupt_not_for_us 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.
