Please prefix the title with "ath6kl: ". Also Signed-off-by is missing. In the title you mention a bit about the bug you are fixing, but it would be useful to describe more about it in the commit log. From user's point of view, how did ath6kl behave before your patch and how will it change after your patch? -- Kalle Valo _______________________________________________ ath6kl mailing list ath6kl@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/ath6kl
