The tags block should not have extra newlines like there's now one in 
between Closes and Signed-off-by.

For patches 1-2:

Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@...ux.intel.com>

(In case you end up submitting a new version, you should collect the tags 
other people have given you, except e.g., if you did major modifications 
to the patch.)
