From 39c9ce70f13a3127a8057e30b48a239bf08f7c8e Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Sun, 29 Oct 2017 13:55:12 +0800 Subject: [PATCH] gma500: mmu: unmap the correct address 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.
