Juergen Borleis ba3abe3f82 dmaengine: imx-dma: configure the generic DMA type to make it work
[ Upstream commit 7199ddede9f0f2f68d41e6928e1c6c4bca9c39c0 ]

Commit dea7a9fbb0 ("dmaengine: imx-dma: remove dma_slave_config
direction usage") changes the method from a "configuration when called"
to an "configuration when used". Due to this, only the cyclic DMA type
gets configured correctly, while the generic DMA type is left
non-configured.

Without this additional call, the struct imxdma_channel::word_size member
is stuck at DMA_SLAVE_BUSWIDTH_UNDEFINED and imxdma_prep_slave_sg() always
returns NULL.

README

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.
