Subject: KVM: arm/arm64: Get rid of unused arg in cpu_init_hyp_mode()
Patch-mainline: v5.5-rc3
Git-commit: 7e0befd521b6d40af1d08fcdb29d4dbf30236624
References: bsc#1133021

As arg dummy is not really needed, there's no need to pass
NULL when calling cpu_init_hyp_mode(). So clean it up.

Fixes: 67f691976662 ("arm64: kvm: allows kvm cpu hotplug")
