Subject: [RESEND PATCH v8 03/10] serial: sc16is7xx: remove obsolete out_thread label

From: Hugo Villeneuve <hvilleneuve@...onoff.com>

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.
