parisc: Make struct parisc_driver::remove() return void
The caller of this function (parisc_driver_remove() in arch/parisc/kernel/drivers.c) ignores the return value, so better don't return any value at all to not wake wrong expectations in driver authors. The only function that could return a non-zero value before was ipmi_parisc_remove() which returns the return value of ipmi_si_remove_by_dev(). Make this function return void, too, as for all other callers the value is ignored, too. Also fold in a small checkpatch fix for: WARNING: Unnecessary space before function pointer arguments + void (*remove) (struct parisc_device *dev); Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> (for drivers/input) Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Acked-by: Jiri Slaby <jirislaby@kernel.org> Signed-off-by: Helge Deller <deller@gmx.de>
