[PATCH] KVM: arm64: Pass on SVE mapping failures

From: James Clark
Date: Tue Nov 12 2024 - 06:20:31 EST


This function can fail but its return value isn't passed onto the
caller. Presumably this could result in a broken state.

Fixes: 66d5b53e20a6 ("KVM: arm64: Allocate memory mapped at hyp for host sve state in pKVM")
