From b1c50ac25425385b576dd58b7b38c1c5963dde85 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 19 Sep 2023 15:32:07 +0200 Subject: dmaengine: xilinx: zynqmp_dma: 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 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() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
