6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabio Estevam festevam@denx.de
commit 2b0a5a8a397c0ae8f8cd25e7d3857c749239ceb8 upstream.
Since commit bfac19e239a7 ("fbdev: mx3fb: Remove the driver") backlight is no longer functional.
The fbdev mx3fb driver used to automatically select CONFIG_BACKLIGHT_CLASS_DEVICE.
Now that the mx3fb driver has been removed, enable the CONFIG_BACKLIGHT_CLASS_DEVICE option so that backlight can still work by default.
Tested on a imx6dl-sabresd board.
