Subject[PATCH AUTOSEL 4.14 27/35] iommu/vt-d: Use memunmap to free memremap
Date
From: Pan Bian <bianpan2016@163.com>

[ Upstream commit 829383e183728dec7ed9150b949cd6de64127809 ]

memunmap() should be used to free the return of memremap(), not
iounmap().

Fixes: dfddb969edf0 ('iommu/vt-d: Switch from ioremap_cache to memremap')
