spi: spi-fsl-dspi: Fix crash when not using GPIO chip select
Summary
In the Linux kernel, the following vulnerability has been resolved: spi: spi-fsl-dspi: Fix crash when not using GPIO chip select Add check for the return value of spi_get_csgpiod() to avoid passing a NULL pointer to gpiod_direction_output(), preventing a crash when GPIO chip select is not used.
