Pavel, who exactly wants this and why? Looking at today's -next I see:

dtor@dtor-ws:~/kernel/linux-next ((next-20190404))$ git grep
"::kbd_backlight" | wc -l
18
dtor@dtor-ws:~/kernel/linux-next ((next-20190404))$ git grep
"platform::kbd_backlight" | wc -l
0

so there isn't a single instance of "platform::kbd_backlight" and we
definitely not changing existing names.

Thanks.
