Hello

Currently writting down a pci driver, I notice that
"pci_register_driver(&pci_driver)" don't forward my "probe" function
errors.
Actually errors are noticed in the kernel ring buffer but don't make
pci_register_driver  fail. It returns a zero value in any case.
I traced back to the kernel in order to try to understand this problem
and find the "void driver_attach(struct device_driver * drv)" function
in the "linux-2.6.11.10/drivers/base/bus.c" file which, obviously, can
not returns an error.

So I just wish to know why this function only print this message :

                               /* driver matched but the probe failed */
                               printk(KERN_WARNING
                                   "%s: probe of %s failed with error %d\n",
                                   drv->name, dev->bus_id, error);

but don't return the error.
Actually I don't understand why the module is loaded (because
pci_register_driver, which is called during __init, don't fail) while
my pci card could not have been initialized by "probe" function
because it failed for such reasons.

Thanks
