Subject: Re: [PATCH 03/16] wireless: ath: convert tasklets to use new
 tasklet_setup() API

Hello,

looking at the other patches in this series, I think this patch's 
subject "ath:" tag was supposed to be "carl9170:"?

(so the full subject is:
"wireless: carl9170: convert tasklets to use new tasklet_setup() API")
