On Buffalo WXR-5590AX12, some LEDs don't have "function" property and
only "color" property is available for the newer binding of LED on
Linux Kernel.
2e659930d3 ("qualcommax: drop redundant label with new LED
color/function format") removes "label" property from LEDs, then,
multiple "<color>:" (ex.: "white:"/"red:") will be appeared as LED names
and renamed to "<color>:_<num>" ("ex.: "white:_1", "green:_2", ...) by
kernel.
logs:
[ 5.372863] leds-gpio leds: Led white: renamed to white:_1 due to name collision
[ 5.375796] leds-gpio leds: Led red: renamed to red:_1 due to name collision
/sys/class/leds:
root@OpenWrt:/# ls /sys/class/leds/
red: red:power white: white:power
red:_1 red:wlan white:_1 white:wlan
Fix this issue by adding missing "function" property to LEDs on Buffalo
WXR-5950AX12.
Note: there are no appropriate functions in dt-bindings/leds/common.h
for some LEDs, so use the hardcoded strings for them instead.
