From dde0a31863d6a7b05ca7cb5d138586e71afc5e50 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 13 Jul 2021 21:35:18 +0200 Subject: PCI: endpoint: Make struct pci_epf_driver::remove 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 pci_epf_device_remove() (because there is only little it can do when a device disappears) and there are no pci_epf_drivers with a remove callback. So make it impossible for future drivers to return an unused error code by changing the remove prototype to return void. The real motivation for this change is the quest to make struct bus_type::remove return void, too.
