From e190a0c389e60178fba3d532abf936dcae223e7d Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 8 May 2023 22:51:38 +0200 Subject: i2c: 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.
