Check for return value from various snd_soc_dapm_* calls, as many of them can return errors and this should be handled. Also, reintroduce the allocation failure check for rt5645->eq_param as well. Make all areas where return values are checked lead to the end of the function in the case of an error. Finally, introduce a comment explaining how resources here are actually eventually cleaned up by the caller.

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.
