Also I think this condition needs to expand to handle the case whether pwr
!= PWR_NONE and !PWR_LED(ctrl) is true.
you need to return for case, pwr = PWR_ON, !PWR_LED(ctrl)=true ,
!ATTN_LED(ctrl)=false, attn=on
Why should we return in that case? We need to update the Attention
Indicator Control to On.
Attempting to PWR_ON when !PWR_LED(ctrl) is true is incorrect right ?
Even if you don't want to return (to handle ATTN part of the function),
may be you should skip updating PWR mask and cmd for this case.
Thanks,
