pci: use size stored in proc_dir_entry for proc bus files
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. Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
