Git-commit: 0efb656147e04f26433de5a399d1b03bf00e4ed6
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

In the next patch, we will introduce a new vlv_get_stolen_reserved, so
before we do, make sure checkpatch is happy with the surrounding code.
Sneak in some debug output while we are here.
