## Overview

In the Linux kernel, the following vulnerability has been resolved:

spi: spi-imx: Add check for spi_imx_setupxfer()

Add check for the return value of spi_imx_setupxfer().
spi_imx->rx and spi_imx->tx function pointer can be NULL when
spi_imx_setupxfer() return error, and make NULL pointer dereference.

 Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
