As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message.

phy: intel: phy-intel-lgm-combo: Convert to platform remove callback returning void 2023-03-20T12:44:56+00:00 Uwe Kleine-König u.kleine-koenig@pengutronix.de 2023-03-07T11:58:36+00:00 2637959428c90ee99a2103d6d6a3994602cf9f85 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.
