Commit c8f71b49ee4d ("serial: sc16is7xx: setup GPIO controller later
in probe") moved GPIO setup code later in probe function. Doing so
also required to move ports cleanup code (out_ports label) after the
GPIO cleanup code.

After these moves, the out_thread label becomes misplaced and makes
part of the cleanup code illogical.

This patch remove the now obsolete out_thread label and make GPIO
setup code jump to out_ports label if it fails.

Why is this not ok for stable kernels yet it has a Fixes: tag?

Please fix.

thanks,

Hi,
this is a somewhat particular case. It is a change that "fixes" some
previously unseen consequence in original commit, but that does not
result in any binary change in the end. That is why I decided not to
put in a "stable" tag.

If you want, maybe it would be simpler to remove the "Fixes" tag? I
originally put this tag to have a reference to the original commit, but
since it is already mentioned in the commit log message body, it can be
removed.

Hugo.

Yes, please just remove it, otherwise it will just confuse us.
