 Re: [PATCH 10/12] mailbox: sun6i-msgbox: Convert to platform remove callback
 returning void

> The .remove() callback for a platform driver returns an int which makes
> many driver authors wrongly assume it's possible to do error handling by

> Trivially convert this driver from always returning zero in the remove
