Subject: uclient-http: Close ustream file handle only if allocated
X-Git-Url: http://git.openwrt.org/source.gi%27t?a=commitdiff_plain;h=ae1c656ff041c6f1ccb37b070fa261e0d71f2b12;p=project%2Fuclient.git

uclient-http: Close ustream file handle only if allocated

Since the connection setup in uclient_do_connect can fail before
ustream_init_fd is called we must check the fd was actually allocated
before closing it, else we would close STDIN.
