From 8d27c78b066d6ca383196e414c2ce7657b9e6095 Mon Sep 17 00:00:00 2001 From: mjacob Date: Mon, 23 Sep 2002 05:16:00 +0000 Subject: [PATCH] Recognize the single channel 2Gb card (FC919)- thanks to LSI Logic for pointing this out. In mpt_intr, don't try and pop a reply queue element out *unless* the interrupt status says you might have one.
