 drivers/remoteproc/remoteproc_virtio.c:148:9: error: 'ctx' undeclared

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git linux-next

commit: a965e977a1038cd738f874b5ee8a16d4fa55c64d [6/19] virtio: add context flag to find vqs
config: x86_64-randconfig-x015-201713 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        git checkout a965e977a1038cd738f874b5ee8a16d4fa55c64d
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the vhost/linux-next HEAD d01047cb281d27bcedbf705089bdd38d86d20b01 builds fine.
      It only hurts bisectibility.
