From 22dedf8f4570897f15e156ac5547cef93e802182 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 25 Sep 2023 11:55:07 +0200 Subject: [PATCH] soc/microchip: mpfs-sys-controller: Convert to platform remove callback returning void MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
