This patch creates a common mmci_dma_setup/release which calls dma_setup/release callbacks of mmci_host_ops and manages common features like use_dma... If there is a fallbacks to pio mode, dma functions must check use_dma. error management: -mmci_dmae_setup fail if Tx and Rx dma channels are not defined -qcom_dma_setup fail if one of both dma channels is not defined, Qcom has no specific resource to release, just mmci dmae resource.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
