The panel driver gained support for backlight but fails to link now when that is disabled: drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of': panel-dpi.c:(.text.panel_dpi_probe_of+0xe8): undefined reference to `of_find_backlight_by_node' This adds a dependency like we have for the other panel drivers.
