From 33d6d2bb7e6bf1ec60d1f4982015db8175c4cba9 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 14 Jan 2021 17:40:06 +0100 Subject: ARM: 9049/1: locomo: make locomo bus's remove callback return void 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 locomo_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.
