Subject: [net-next PATCH] tun: correctly report an error in tun_flow_init()
Date: Thu, 06 Dec 2012 10:48:38 -0500 [thread overview]
Message-ID: <20121206154838.6073.17102.stgit@localhost> (raw)
On error, the error code from tun_flow_init() is lost inside
tun_set_iff(), this patch fixes this by assigning the tun_flow_init()
error code to the "err" variable which is returned by
the tun_flow_init() function on error.
