Subject: iommu: Don't use sme_active() in generic code
X-Git-Tag: v5.15~5388^2~11^10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2896ba40d0becdb72b45f096cad70633abc014f6;p=platform%2Fkernel%2Flinux-starfive.git

iommu: Don't use sme_active() in generic code

Switch to the generic function mem_encrypt_active() because
sme_active() is x86 specific and can't be called from
generic code on other platforms than x86.

Fixes: 2cc13bb4f59f ("iommu: Disable passthrough mode when SME is active")
