From 7cffcade57a429667447c4f41d8414bbcf1b3aaa Mon Sep 17 00:00:00 2001 From: Dawei Li Date: Tue, 13 Dec 2022 23:46:52 +0800 Subject: xen: make remove callback of xen driver void returned Since commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller. This change is for xen bus based drivers.
