About module priority

To modify the common prob, I need to rebuild the common driver, but the
driver I am develop is not just for myself, I could ask everyone who will
use this specail sd card to rebuild their driver(or kernel).

So is it possible to modify the priority of prob just calling some existing
kernel APIs?

Sorry missed ur whole details. In that case, u modify the existing driver
and call ur part of ur code from common probe depending on ur special
condition otherwise keep the existing flow.

Hi Arun,

Thanks for your reply.

I have ever thought about this method, but my sd driver is only for my own
special sd card which is not the common sd card and my driver could not
deal with the common sd card. So I need the default sd driver for other
common sd cards.

I hope that mmc core could let my driver probe first, if the sd card is my
special one, my driver will operate it  in my own way, otherwise mmc core
will call the prob function of the default sd driver then.

Hi folks,
I am writing a kernel module for a sd card, but when I insert a sd card
into my box, the default sd driver will probe before my driver, and my
driver will never have chance to probe. Is there any method to make my
driver probe the sd card before the default sd driver?

Why can't you disable  the default sd card driver in your .config?

Thanks in advance.
