I fixed this in the commit message, did a small bikeshed on the single-
if-with-braces and merged the patch.
I downloaded your patch through patchwork and it changed your name
(patch author) from "Oscar Mateo" to "Oscar Mateo Lozano" (then dim
push-queued complained the patch was missing author Signed-off-by due
to the name difference, which made me notice it). You may want to
either fix your name in patchwork so it appears as "Oscar Mateo" or
change your git configuration to add the missing name.
Thanks for the patch and reviews.
Thanks,
Paulo
