Subject: efi/esrt: use memunmap rather kfree to free the remapping
Date:   Sun, 29 Oct 2017 22:51:02 +0800
Message-Id: <1509288662-7880-1-git-send-email-bianpan2016@163.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The remapping result of memremap should be freed with memunmap, not
kfree.
