6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> [ Upstream commit d0b52f6539e008a0d42bf673486bd21b7d2dc191 ] 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
