[patch 1/2] pci: use size stored in proc_dir_entry for proc busfiles

From: David Rientjes
Date: Thu Sep 27 2007 - 16:41:51 EST


On pci_proc_attach_device(), the size of the PCI configuration space is
stored in the proc_dir_entry as the size of the file. Thus, the procfs
interface to PCI devices should use it instead of the device directly.
