From: Nuno Sa <nuno.sa@xxxxxxxxxx> If a device_link is previously created (eg: via fw_devlink_create_devlink()) before the supplier + consumer are both present and bound to their respective drivers, there's no way to set DL_FLAG_AUTOREMOVE_CONSUMER anymore while one can still set DL_FLAG_AUTOREMOVE_SUPPLIER. Hence, rework the flags checks to allow for DL_FLAG_AUTOREMOVE_CONSUMER in the same way DL_FLAG_AUTOREMOVE_SUPPLIER is done. While at it, make sure that we are never left with DL_FLAG_AUTOPROBE_CONSUMER set together with one of DL_FLAG_AUTOREMOVE_CONSUMER or DL_FLAG_AUTOREMOVE_SUPPLIER.
