    linux: Make platform device probe less fragile · 0816e8fc
    Adam Jackson authored
    At the point where xf86BusProbe runs we haven't yet taken our own VT,
    which means we can't perform drm "master" operations on the device. This
    is tragic, because we need master to fish the bus id string out of the
    kernel, which we can only do after drmSetInterfaceVersion, which for
    some reason stores that string on the device not the file handle and
    thus needs master access.
    Fortunately we know the format of the busid string, and it happens to
    almost be the same as the ID_PATH variable from udev. Use that instead
    and stop calling drmSetInterfaceVersion.
