Looks good in general, but I'd prefer one patch per driver
(all in a series for easy applying).

The reason is that these may need to be applied by someone as a
precursor to an actual fix. If we have them as one big set
they have to do considerably more work to use them than if
we keep the patches independent for each of the drivers.

Except in very rare cases we try to avoid patches that cover
multiple otherwise independent bits of code.

Thanks,

Jonathan
