The driver core ignores the return value of struct device_driver::remove
because there is only little that can be done. For the shutdown callback
it's ps3_system_bus_shutdown() which ignores the return value.

To simplify the quest to make struct device_driver::remove return void,
let struct ps3_system_bus_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.

For the sound bit:
Acked-by: Takashi Iwai <redacted>

assuming that you are the one who will apply this patch: Note that it
depends on patch 1 that Takashi already applied to his tree. So you
either have to wait untils patch 1 appears in some tree that you merge
before applying, or you have to take patch 1, too. (With Takashi
optinally dropping it then.)

Best regards
Uwe
