(but each implementation will duplicate checks) Or may have a generic check in the core including rpdev->announce as well (and doing virtio_rpmsg.c clean-up) Change will become: if (rpdev->announce && ept && rpdev->ops->announce_create) Regards, Loic > err = rpdev->ops->announce_create(rpdev); > out: > return err; > -- > 2.16.2 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-remoteproc" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
