It looks like 1s/0s is still the "default", so you could have just
made this old function a wrapper:

static int tps6598x_exec_cmd(struct tps6598x *tps, const char *cmd,
			     size_t in_len, u8 *in_data,
			     size_t out_len, u8 *out_data)
{
        return tps6598x_exec_cmd_tmo(tps, cmd, in_len, in_data, out_len, out_data, 1000, 0);
}

thanks,
