6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Fabio Estevam <festevam@xxxxxxx>
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.
