This feels rather pointless. You are changing these functions to return
an error code but the callers it anyway. And besides, did you check
where these are actually used?
if (at76_debug & DBG_MIB) {
at76_dump_mib_mac(priv);
at76_dump_mib_mac_addr(priv);
at76_dump_mib_mac_mgmt(priv);
at76_dump_mib_mac_wep(priv);
at76_dump_mib_mdomain(priv);
at76_dump_mib_phy(priv);
at76_dump_mib_local(priv);
}
So it's just for debug messages and the current error handling looks the
correct approach. There is not much anything else we can do than just
skip the message printout.
