From c2fa4f4ad8ddf4b9fac344f1da7a25d4868f08f5 Mon Sep 17 00:00:00 2001 From: Adam Kropelin Date: Fri, 16 Sep 2005 19:28:18 -0700 Subject: [PATCH] [PATCH] pciehp: Use dword accessors for PCI_ROM_ADDRESS PCI_ROM_ADDRESS is a 32 bit register and as such should be accessed using pci_bus_{read,write}_config_dword(). A recent audit of drivers/ turned up several cases of byte- and word-sized accesses. The harmful ones were fixed by Linus directly. This patches up one of the remaining harmless-but-still-wrong cases caught in the dragnet.
