Message-Id: <1411136185-28658-1-git-send-email-tklauser@distanz.ch> Date: Fri, 19 Sep 2014 16:16:25 +0200 From: Tobias Klauser <tklauser@...tanz.ch> To: "David S. Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org Subject: [PATCH net] dm9000: Return an ERR_PTR() in all error conditions of dm9000_parse_dt() In one error condition dm9000_parse_dt() returns NULL, however the return value is checked using IS_ERR() in dm9000_probe(), leading to the error not being properly propagated if CONFIG_OF is not enabled or the device tree data is not available. Fix this by also returning an ERR_PTR() in this case.
