Subject: iommu/vt-d: Use memunmap to free memremap
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=829383e183728dec7ed9150b949cd6de64127809;p=openwrt%2Fstaging%2Fblogic.git

iommu/vt-d: Use memunmap to free memremap

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

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