Attempts to compile tilcdc as module results in:
drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here make[5]: [drivers/gpu/drm/tilcdc/tilcdc.o] Error 1 (ignored)
It appears it was never even tried to build it as module, or the problem would have been seen. So running this driver as module was never really tested. Disable it. If really needed, the code wil require some structural changes and in-depth testing, which can and should be done separately.
