Those were removed when LED pattern interface was changed to generic firmware interface. Please refer to commits below. git commit 9ce7cb170f97f83a78dc948bf7d25690f15e1328 (leds-lp5521: use generic firmware interface) git commit db6eaf8388a413a5ee1b4547ce78506b9c6456b0 (leds-lp5523: use generic firmware interface) Necessary attributes are restored in this patch-set.
