TMS570LS1224: SPI Code

I am using TMS570LS1224 device and configured with HalCogen and CCS.

The code for SPI daisy chain have been given below.

I am getting the below warnings in the code.

Please tell me how to correct these warnings. How to optimize the below code in a better way?

Can you please give sample for SPI daisy chain code?

Code:

/* USER CODE BEGIN (0) */
/* USER CODE END */

/* Include Files */

#include "sys_common.h"

/* USER CODE BEGIN (1) */
#include "mibspi.h"
/* USER CODE END */

/** @fn void main(void)
*   @brief Application main function
*   @note This function is empty by default.
*
*   This function is called after startup.
*   The user can use this function to implement the application.
