PATCH 1/1 usb: typec: silence a static checker warning
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.
