From fc7a6209d5710618eb4f72a77cd81b8d694ecf89 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 13 Jul 2021 21:35:22 +0200 Subject: bus: Make remove callback return void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.
