From 1187ece3db310cb1e7cd75083dc7253dbac39675 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 8 Dec 2006 02:38:10 -0800 Subject: [PATCH] [PATCH] mxser: PCI refcounts Switch to pci ref counts for mxser when handling PCI devices. Use pci_get_device and drop the reference when we finish and unload.
