Here you call omap2_mcspi_get_slave_ctrldata function that allocate
memory for cd structure, but this memory never freed.
Also, why do you read DT data in omap2_mcspi_setup_transfer function?
Under certain conditions the omap2_mcspi_setup_transfer function may be
calling for each transfer and each call it will check (!cd &&
spi->dev.of_node) condition.
Consider to move DT data read code from omap2_mcspi_setup_transfer to
omap2_mcspi_setup function and free spi->controller_data pointer in
omap2_mcspi_cleanup function.
