We also need the following incremental change to prevent
panel-dsi-cm trying to use of_find_backlight_by_node().
We have ledtrig-backlight use FB_EVENT_BLANK, and I
guess more events can be added there as needed.

There should be no dependency to the driver changes with
this patch, so it's probably best that I queue this dts
patch separately. I'll fold in the following change too
assuming no more comments.

Regards,

Tony
