From e898d9cdd3a9f105863d63dd3b46443742a4757c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 20 Dec 2018 18:19:44 +0100 Subject: mailbox: Add device-managed registration functions Add device-managed equivalents of the mbox_controller_register() and mbox_controller_unregister() functions that can be used to have the devres infrastructure automatically unregister mailbox controllers on driver probe failure or driver removal. This can help remove a lot of boiler plate code from drivers.
