Swati Agarwal 229769759e dmaengine: xilinx_dma: Report error in case of dma_set_mask_and_coherent API failure 
[ Upstream commit 8f2b6bc79c ]

The driver does not handle the failure case while calling
dma_set_mask_and_coherent API.

In case of failure, capture the return value of API and then report an
error.

Addresses-coverity: Unchecked return value (CHECKED_RETURN)

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.
