Subject: [PATCH] usb: typec: silence a static checker warning
Date: Wed, 14 Apr 2021 10:44:40 +0300 [thread overview]
Message-ID: <YHadaACH8Mq/10F7@mwanda> (raw)
Smatch complains about a potential missing error code:
drivers/usb/typec/port-mapper.c:168 typec_link_port()
warn: missing error code 'ret'
This is a false positive and returning zero is intentional. Let's
re-arrange the code to silence the warning and make the intent more
clear.
