Subject: [PATCH 04/11] Revert "HID: playstation: add DualSense player LEDs support."

From: Roderick Colenbrander <roderick.colenbrander@...y.com>

This reverts commit c240f0cb88ec ("HID: playstation: add
DualSense player LEDs 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.
