mipi_dsi_attach is allowed to fail, and currently the probe code doesn't clean up (mainly drm_panel_remove) if this happens. Add cleanup code on failure. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
The panel sends MIPI DCS commands during prepare and is expecting the bus to remain in LP-11 state in-between. Set the prepare_upstream_first flag so that the upstream DSI host is prepared / pre_enabled first, and therefore the bus is in a defined state.
