I suspect this one is superseded by your new patch series
http://patchwork.ozlabs.org/project/buildroot/list/?series=63524, so
I've marked this patch as Changes Requested.

Note that
http://patchwork.ozlabs.org/project/buildroot/list/?series=63524
doesn't contain PATCH 2/3 due to a patchwork issue when associating
patches to series, but PATCH 2/3 has been recorded by patchwork.

Best regards,

Thomas
