In the context of enabling the discovery of the PHYs which have the C45 MDIO address space in a non-standard address: num_ids in get_phy_c45_ids, has the value 8 (ARRAY_SIZE(c45_ids->device_ids)), but the u32 *devs can store 32 devices in the bitfield. If a device is stored in *devs, in bits 32 to 9 (bit counting in lookup loop starts from 1), it will not be found.
