From f6c80082b4132a38d39326730abaedfe844847b8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 13 May 2026 15:34:13 -0400 Subject: [PATCH] spi: spi-ti-qspi: Convert to platform remove callback returning void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 2f2802d1a59d79a3d00cb429841db502c2bbc3df ] 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(). Add an error message to the error path that returned an error before to replace the core's error message with more information. Apart from the different wording of the error message, this patch doesn't introduce a semantic difference.
