Hi Stephen,
Absolutely, my patch is wrong ; comment below explains struct is filled
afterwards.Sorry.
Greg, should I send you a revert or maybe we could standardize that driver ? (it
seems it's the only one to work that way).
static const struct of_device_id uio_of_genirq_match[] = {
{ /* This is filled with module_parm */ },
{ /* Sentinel */ },
};
Regards,
Fabian
