From: Roderick Colenbrander <roderick.colenbrander@xxxxxxxx>
This reverts commit ebbe998a4a52 ("HID: playstation: add
DualSense lightbar support")
There is currently an ongoing discussion on linux-leds LKML,
and so to give us more room, we need to revert those related
patches from linux-next.
This is not a big deal, they are still not pushed to Linus.
