I prefer to have this fixed by setting
.suppress_bind_attrs = true
in the struct device_driver .drv portion of the device driver,
so the driver cannot be removed from sysfs.

So platform_driver_probe() isn't really the only exception,
there is a way to do the same supression on ordinary drivers
if we know we won't fiddle with them from sysfs.

Can you make a patch as per above (alternatively tell me
how wrong I am...)

Yours,
Linus Walleij
