From 94a1150421940ff2e8113b5fa6837774777d5b3d Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:29:13 +0100 Subject: [PATCH] vhost-vdpa: vhost_vdpa_alloc_domain() should be using a const struct bus_type * The function, vhost_vdpa_alloc_domain(), has a pointer to a struct bus_type, but it should be constant as the function it passes it to expects it to be const, and the vhost code does not modify it in any way.
