Subject: [PATCH] power: supply: rt9467: Fix rt9467_run_aicl()
Date:   Wed, 15 Feb 2023 13:43:04 +0100
Message-Id: <2ed01020fa8a135c36dbaa871095ded47d926507.1676464968.git.christophe.jaillet@wanadoo.fr>

It is spurious to bail-out on a wait_for_completion_timeout() call that
does NOT timeout.

Reverse the logic to return -ETIMEDOUT instead, in case of tiemout.

Fixes: 6f7f70e3a8dd ("power: supply: rt9467: Add Richtek RT9467 charger driver")

Compile tested only.

This is spurious, because if I'm right, it means that it does not work!
Testing on a real hardware is really welcomed.
