From 507deb25db624c97c3296d03f2367a0f87caab04 Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Wed, 19 Jul 2017 14:42:28 +0300 Subject: [PATCH] staging: fsl-mc: fix compilation with non-generic msi domain ops The bus driver relies on generic msi domain ops. Fix compilation for architectures that don't provide it (e.g. x86_64).
