Subject: gma500: mmu: unmap the correct address
Git-commit: 39c9ce70f13a3127a8057e30b48a239bf08f7c8e
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The function kunmap_atomatic() is called on the same variable twice,
i.e. pt->v. In the second call, its parameter should be variable v
rather than pt->v.
