Martin Blumenstingl 195b2919cc net: stmmac: manage errors returned by of_get_mac_address() ... Commit d01f449c00 ("of_net: add NVMEM support to of_get_mac_address") added support for reading the MAC address from an nvmem-cell. This required changing the logic to return an error pointer upon failure. If stmmac is loaded before the nvmem provider driver then of_get_mac_address() return an error pointer with -EPROBE_DEFER. Propagate this error so the stmmac driver will be probed again after the nvmem provider driver is loaded. Default to a random generated MAC address in case of any other error, instead of using the error pointer as MAC address.
