The commit message sounds a bit obscure to me. You say the 
led_brightness enumeration is or rather will become obsolete. I don't 
understand the reason given "led class now supports max_brightness". 
What does that mean?

Also I do not understand the approach here. If the enum is obsolete why 
not start with the APIs using it like the led callbacks 
brightness_{get,set{,_blocking}}. I suspect that is your next step, but 
it seems like unnecessary churn to me.

Anyway, what triggered me to look at this is the fact that we do have a 
led.c under drivers/net/wireless/broadcom/brcm80211/brcmsmac 
implementing the brightness_set() callback.

Regards,
Arend
