Can you please tell a bit more what these LEDs are actually used for ?
Do they have some names or symbols ? Are they also controlled by
something else (e.g. numlock or shiftlock leds)

They're used for the keyboard backlight. This functionality is pretty 
common on gaming laptops.

hmm, keyboard backlight ... don't we already have something for that
in input subsys ? I believe that some lone LEDs aren't the right subsys
for those stuff.

CC'ing linux-input list: guys, could you have a look at this ? is input
sysbsys already capable of handling this ?
