Subject: [PATCH] KVM: arm64: vgic: Remove duplicate check in update_affinity_collection()
Date: Fri, 23 Sep 2022 14:54:47 +0800	[thread overview]
Message-ID: <20220923065447.323445-1-gshan@redhat.com> (raw)

The ITS collection is guranteed to be !NULL when update_affinity_collection()
is called. So we needn't check ITE's collection with NULL because the
check has been included to the later one.

Remove the duplicate check in update_affinity_collection().
