Subject: [PATCH 0/3] KVM: arm64: fix warnings in W=1 build

Building arch/arm64/kvm/ with W=1 spills out a lot of warnings. When
changing stuff I try to use as much tooling as possible to make sure
that I don't screw up - having a clean baseline imho helps with that.

With the first 2 patches applied make W=1 arch/arm64/kvm/ runs without
warnings for me (fedora userspace, kvm-arm/next). Patch 3 gets rid
of sparse lock warnings in arch/arm64/kvm/vgic/.

Sebastian Ott (3):
  KVM: arm64: fix override-init warnings in W=1 builds
  KVM: arm64: fix kdoc warnings in W=1 builds
  KVM: arm64: vgic: fix unexpected unlock sparse warnings
