parentr8169: fix an if condition (diff)
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.
