No this is not the mistake. The patch changes the function udc_init
in /drivers/usb/gadget/pxa27x_udc.c to:
static int __init udc_init(void)
{
if (!cpu_is_pxa27x() && !cpu_is_pxa3xx())
return -ENODEV;
printk(KERN_INFO "%s: version %s\n", driver_name, DRIVER_VERSION);
return platform_driver_probe(&udc_driver, pxa_udc_probe);
}
The line
printk(KERN_INFO "%s: version %s\n", driver_name, DRIVER_VERSION);
gets printed out (I see it with dmesg).
The error comes from the function platform_driver_probe
in /drivers/base/platform.c, which is apparently a standard function of
the kernel, and not hardware specific. Would it help, if I tell you exactly which functions go wrong? I still think, that the error must be elsewhere, not in these standard functions. But where? Is only a file in
the file system of my board missing?

No, in the file .config it is set to
CONFIG_CPU_PXA320=y
Any other ideas please?
Best regards.
