Hi,

Earlier this year Sony published a new driver 'hid-playstation' to support
our new DualSense controller. During the review process, the maintainers
of the LED subsystem expressed that they wanted to be more strict about LED
naming moving forward. There was little time to make the necessary changes
for Linux 5.12 at the time, so LED support was taken out for Linux 5.12.

This patch set adds support for the DualSense lightbar and player LEDs
based on previous patches, but using a new naming scheme.

The DualSense lightbar is exposed using a multi-color LED and is named
after the 'main' input device and uses a name like "inputX:rgb:indicator".

The player LEDs didn't have a suitable "function" type defined by the LED
subsystem. This patch series introduces a new "LED_FUNCTION_PLAYER" type
for these LEDs. This type is then used for 'hid-playstation' and long-term
will be used by 'hid-nintendo' as well. The overall naming takes the form:
"inputX:white:player-1" for the first player LED on a DualSense controller.
