Lubomir Rintel 6c414ddee7 dmaengine: mmp_tdma: Do not ignore slave config validation errors
[ Upstream commit 363c32701c7fdc8265a84b21a6a4f45d1202b9ca ]

With an invalid dma_slave_config set previously,
mmp_tdma_prep_dma_cyclic() would detect an error whilst configuring the
channel, but proceed happily on:

  [  120.756530] mmp-tdma d42a0800.adma: mmp_tdma: unknown burst size.

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.
