[PATCH 5/9] um/drivers/vector_user: Delete two unnecessary checks before freeaddrinfo() in user_init_socket_fds()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 11 Mar 2018 14:20:46 +0100

The implementation returns from this function if a null pointer
was detected in the local variable "gairesult". Thus the check
before two calls of the function "freeaddrinfo" is not needed.
