The driver core ignores the return value of struct bus_type::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct locomo_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

Hello,

if desired the change to arch/arm/mach-sa1100/collie.c can be split out
of this patch. The change of prototype then doesn't affect this driver
any more. There is one locomo-driver that is already now unaffected:
drivers/leds/leds-locomo.c. This driver doesn't have a remove callback.

Best regards
Uwe
