From 3a2ab02ddfacb04f92d47f2fe6e4aef4c95366e4 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sun, 19 Mar 2023 00:54:02 +0100 Subject: fbdev: mb862xx: Convert to platform remove callback returning void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
