Is this necessary now that you're not enabling uart1?
But otherwise:
Acked-by: Andrew Jeffery <andrew@...id.au>
However, I'm guessing you copy/pasted the patch as we still have the
reply text at the bottom. Copy/paste can lead to mangled whitespace
or other errors that prevent the patch from being applied cleanly. I
recommend getting set up and familiar with `git send-email` to give
your patch the best chance of being applied without trouble. The
`git format-patch` / `git send-email` pair also take care of iterating
on your patch with e.g. the `-v` switch that injects the version number
of the patch in the appropriate places.
