Agreed, returning early lets callers free memory the device may still
DMA into.

For a device that is present but never completes the reset, would it
be acceptable to fence it instead: pci_clear_master() after a bounded wait,
and pci_set_master() only once a later reset completes? .reset would
then always return with the device quiet, so caller can keep ignoring
the result.

Will do, v2 will use the present APIs.

Thanks,
