[gpsd-dev] [PATCH v3 1/1] gps2udp: reset errno after successful getaddrinfo call

[Ferry Huberts]

From: Ferry Huberts <address@hidden>

It may return errno==2 ("No such file or directory") when the file
/etc/gai.conf is not present.

The observed effect was that the port number conversion considered
a perfectly valid port number as invalid.
