[PATCH 0/4] KVM: VFIO: use mutex guards to simplify control flow

["Carlos López" <clopez@suse.de>]

Replace several uses of mutex_lock() / mutex_unlock() pairs with mutex
guards, allowing removal of all gotos in virt/kvm/vfio.c.

In this series I also include a small refactor that allows greatly
simplifying kvm_vfio_file_del(), and skipping an unnecessary call to
kvm_vfio_update_coherency() if the list of files managed by the KVM
VFIO device does not change.

Carlos López (4):
  KVM: VFIO: clean up control flow in kvm_vfio_file_add()
  KVM: VFIO: use mutex guard in kvm_vfio_file_set_spapr_tce()
  KVM: VFIO: deduplicate file release logic
  KVM: VFIO: update coherency only if file was deleted
