    video: exynos: fix modular build · 5a63ddf6
    Arnd Bergmann authored
    The s6e8ax0 driver has a dependency on BACKLIGHT_CLASS_DEVICE,
    which can be configured as a loadable module, so we have to
    make the driver a tristate symbol as well, to avoid this error:
    
    drivers/built-in.o: In function `s6e8ax0_probe':
    :(.text+0x23a48): undefined reference to `devm_backlight_device_register'
    
    This also means we get another error from a missing export, which
    this fixes as well:
    
    ERROR: "exynos_mipi_dsi_register_lcd_driver" [drivers/video/fbdev/exynos/s6e8ax0.ko] undefined!
    
    The drivers are all written to be loadable modules already,
    except the Kconfig options for that are missing, which makes
    the patch really easy.
    
    Finally, the EXYNOS_VIDEO option is turned into tristate as well
    for good measure, as all framebuffer drivers should be configurable
    as modules, though this change is not strictly necessary.
