It is not an addition. I just moved "pr_info("driver registered.\n")" from gpmi_nand_init, (which is removed by this patch) to the probe function. Regards, Fabio Estevam

I'd say drop it completely then, there's now value in this print (or make it pr_debug() ). Besides, the init call was called only once if compiled in / every time if built as a module. The probe call is done per GPMI nand driver instance. > Regards, > > Fabio Estevam Best regards, Marek Vasut

Besides, the init call was called only once if I think we can keep this info. It does not hurt and this is how the current driver does. > compiled in / every time if built as a module.
