From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> Date: Wed, 5 May 2021 22:14:49 +0200 > 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 vio_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 should prevent > that future driver authors consider returning an error code. > > Note there are two nominally different implementations for a vio bus: > one in arch/sparc/kernel/vio.c and the other in > arch/powerpc/platforms/pseries/vio.c. This patch only addresses the > former. > > Signed-off-by: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> Acked-by: David S. Miller <davem@xxxxxxxxxxxxx>
