    PCI: Change all drivers to use pci_device->revision · 44c10138
    Auke Kok authored
    Instead of all drivers reading pci config space to get the revision
    ID, they can now use the pci_device->revision member.
    This exposes some issues where drivers where reading a word or a dword
    for the revision number, and adding useless error-handling around the
    read. Some drivers even just read it for no purpose of all.
    In devices where the revision ID is being copied over and used in what
    appears to be the equivalent of hotpath, I have left the copy code
    and the cached copy as not to influence the driver's performance.
    Compile tested with make all{yes,mod}config on x86_64 and i386.
