  [PATCH 1/2] drm/virtio: kconfig: Fix recursive dependency issue. Peter Griffin <peter.griffin@linaro.org> - 2016-09-19 11:40 +0200

#1486301 — [PATCH 1/2] drm/virtio: kconfig: Fix recursive dependency issue.

ST_SLIM_REMOTEPROC must select REMOTEPROC, which exposes the following
recursive dependency.

which is due to drivers/gpu/drm/virtio/Kconfig depending on VIRTIO.

Fix by dropping depend and switching to select VIRTIO.
