From 6d247e4d264961aa3b871290f9b11a48d5a567f2 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 26 Nov 2020 17:59:50 +0100 Subject: powerpc/ps3: make system bus's remove and shutdown callbacks return void 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.
