From 794f5bfa77955c4455f6d72d8b0e2bee25f1ff0c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig <hch@lst.de> Date: Fri, 17 Jun 2005 12:25:25 -0700 Subject: [PATCH] [PATCH] PCI: don't override drv->shutdown unconditionally There are many drivers that have been setting the generic driver model level shutdown callback, and pci thus must not override it. Without this patch we can have really bad data loss on various raid controllers.
