compat: keep printing pci revision on older kernels
From: Trent Piepho <xyzzy@speakeasy.org>
In 2.6.23, there is a new struct pci_dev->revision field to get the pci
revision. A couple drivers now use this to print the revision and on old
kernels don't print it anymore. This patch adds a simple function to get
the revision to compat.h to make it easy for the backward compay code to
keep printing the revision like is used too.
