The call to of_find_matching_node returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: drivers/gpu/drm/omapdrm/dss/omapdss-boot-init.c:212:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 209, but without a corresponding object release within this function. drivers/gpu/drm/omapdrm/dss/omapdss-boot-init.c:237:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 209, but without a corresponding object release within this function.

To complement panel-simple.yaml, create panel-simple-dsi.yaml. panel-simple-dsi-yaml are for all simple DSP panels with a single power-supply and optional backlight / enable GPIO. Migrate panasonic,vvx10f034n00 over to the new file.

The handling of virtqueue_add_sgs ENOSPC error is incorrect because it can result in out-of-order virtqueue_add_sgs and break fences. We never get ENOSPC anyway because the caller waits until there is enough space (the other caller that did not wait was removed in commit 32d6c2c5 ("drm/virtio: Rewrite virtio_gpu_queue_ctrl_buffer using fenced version.")). Remove the incorrect and unnecessary error path. This also adds a WARN_ON(ret) until we properly handle errors. Signed-off-by:
