Subject: [PATCH v8 03/10] serial: sc16is7xx: remove obsolete out_thread label
Date: Wed,  7 Jun 2023 10:05:17 -0400	[thread overview]
Message-ID: <20230607140525.833982-4-hugo@hugovil.com> (raw)
In-Reply-To: <20230607140525.833982-1-hugo@hugovil.com>

From: Hugo Villeneuve <hvilleneuve@dimonoff.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.

Fixes: c8f71b49ee4d ("serial: sc16is7xx: setup GPIO controller later in probe")
Signed-off-by: Hugo Villeneuve <hvilleneuve@dimonoff.com>

I put a "Fixes" tag, even if the patch doesn't fix a "real" bug.

It could have been merged with later patch 6/10, but then the explanation
for the change would have been somewhat lost in the noise, and I think it
is important to clearly state in the logs why this change was done, to fix
a "logical" regression introduced by a previous patch.

I can remove the tag if it is deemed non appropriate.
