Subject: Re: [PATCH -next] drivers: net: CONFIG_ATH9K select LEDS_CLASS

hello Pavel，thanks for your reply.

for  the a point, I don't know the led lists and cannot find it.

for the b point, I look other configs who select LEDS_CLASS, almost all 
of them select NEW_LEDS，maybe you are right, CONFIG_ATH9K also need 
select NEW_LEDS too.


Best regards,

Zhang Jianhua
