[ Upstream commit 0ebbd45c33d0049ebf5a22c1434567f0c420b333 ]
bcm63xx_soc_pcm_new() does not check the return value of
of_dma_configure(), which may fail with -EPROBE_DEFER or
other errors, allowing PCM setup to continue with incomplete
DMA configuration.
Add error checking for of_dma_configure() and return on failure.
Fixes: 88eb404ccc ("ASoC: brcm: Add DSL/PON SoC audio driver")

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.
