It looks like spidev_class was uninitialised because spidev_init() had not yet been called. To force spidev_init() to be called before my SPI Controller's driver initialisation, I just used: subsys_initcall(spidev_init); This seems to do the job... _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
