on libubox/usock.c:

poll_restart() is trying to use the return of poll() as if it were errno.

This renders the error paths in that function ineffective, and most likely result in errors being hidden. The function will spin around until it times out, and mask the real error.

This impacts the "happy eyeballs" code on usock_inet_timeout(), plus any other users of poll_restart().
