Both omap2_mcspi_tx_dma() and omap2_mcspi_rx_dma() are only called from omap2_mcspi_txrx_dma() and omap2_mcspi_txrx_dma() is always called after making sure that mcspi_dma->dma_rx and mcspi_dma->dma_tx are not NULL (see omap2_mcspi_transfer_one()). Therefore remove redundant NULL checks for omap2_mcspi->dma_tx and omap2_mcspi->dma_rx pointers in omap2_mcspi_tx_dma() and omap2_mcspi_rx_dma() respectively.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
