Merge tag 'rproc-v4.16' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This contains a few bug fixes and a cleanup up of the resource-table
  handling in the framework, which removes the need for drivers with no
  resource table to provide a fake one"

* tag 'rproc-v4.16' of git://github.com/andersson/remoteproc:
  remoteproc: Reset table_ptr on stop
  remoteproc: Drop dangling find_rsc_table dummies
  remoteproc: Move resource table load logic to find
  remoteproc: Don't handle empty resource table
  remoteproc: Merge rproc_ops and rproc_fw_ops
  remoteproc: Clone rproc_ops in rproc_alloc()
  remoteproc: Cache resource table size
  remoteproc: Remove depricated crash completion
  virtio_remoteproc: correct put_device virtio_device.dev
