[1/1] wifi: ath9k: return by of_get_mac_address commit: dfffb317519f88534bb82797f055f0a2fd867e7b Best regards,

When using nvmem, ath9k could potentially be loaded before nvmem, which loads after mtd. This is an issue if DT contains an nvmem mac address. If nvmem is not ready in time for ath9k, -EPROBE_DEFER is returned. Pass it to _probe so that ath9k can properly grab a potentially present MAC address.
