You can't implement this function in a way that the caller cannot determine that it didn't actually do anything. You either have to protect calls with ifdefs or make this routine return an error indication, in response to which the caller can set a random ethernet address or take some other corrective action. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

An error code return value could be added, but it didn't seem necessary.

David, I could change that function to return an error code in this case, but this stub should never get called, because a caller should check if this device is a ssb gige core with pdev_is_ssb_gige_core() before and this always returns false if CONFIG_SSB_DRIVER_GIGE is not set. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iQIcBAEBAgAGBQJQ8zXWAAoJEIZ0px9YPRMyFgEP/Rz1BOXwbHawvupAWKCLdhm5 UquCnygVZrsbskN63c5R4OfVXGZ6UFihbf1xKHq4IRv9UXkNdymoiCmv6sUVfkjR FemyqRZ4QOz08cbVhb0k0nEIpVguyf16063kGo4JHIGAZc54xruMZv54uZYOfvvR GYbTsVbkzNvW2ArVesGGYjbKHyEyOmjqW5GvjyyH72cQK+vZI8PBRC8tO9l8d3D1 pq3KnHSeOEXBbODgWC36QmcMV8EEQ4BAxJQjsABXO7KRyu0HpAu7zSEn8aGhV4ln X1q6WMzPQIOjJhmxJUGbnJEo1s05/AjT2lIU7J7QcHN21YQqIUjWzG9lYCWcbhX/ RloFjEk/Gf80CfzJj97RCLKiJScfa8tdbvFvisDZaQVbet7Ql5nHeRSyiMTzMFKi oivkh3gmaN/2CE8rgj5QIiL3DSzy0MY2cbTZMx3QmYAlTQ52cTT3NLRaT5RKxv3c gAUq0EvkOZhHKo/WkBWbI/V4p4CWNhJI/wNphHuOM7lJ3kvfITXw17+/29rywkZY pB5TwdlQBtuRUjAbXvUJmfIAZE1p4bd9+0liW+qPlpoa1d7ZOaTWPhxUg+74kvgP rItNpGf9RAb7/A/n9XjciemihcMpEH4BjShgJVNN66+LwfbQ2ZRNGsJfyJZGcYEO n7qAWVoPmgKihES59NtA =1JMZ -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
