yes, it's better. just need to import the match lib.
I will change to this and sent v2 patch. Thanks.

BTW: speak of patman, I get an issue of using the "Series-prefix".

When I use Series-prefix like following in the commit:
     Series-prefix: U-Boot][
Then I get the patman generated patch like:
     [U-Boot][ PATCH]
                     ^  a space here.

A space is before the 'PATCH', that annoys me. But I don't see you have 
such space in your patches. Any advice to avoid the extra space?
Thanks in advance.

Josh Wu
