On built-in kernels this warning will always splat, even if no ivtvfb
hardware is present, as this is part of the module init:
if (WARN(pat_enabled(),
"ivtvfb needs PAT disabled, boot with nopat kernel parameter\n")) {
Fix that by shifting the PAT requirement check out under the code
that does the "quasi-probe" for the device.
This device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then uses
driver_for_each_device() to try to see if it can probe each of those
devices as a frambuffer device with ivtvfb_init_card().
We tuck the PAT requiremenet check then on the ivtvfb_init_card() call
making the check at least require an ivtv device present before
complaining.
