According to usage (bitfields.h) of REG_FIELDS,
Modify is:
reg &= ~REG_FIELD_C;
reg |= FIELD_PREP(REG_FIELD_C, c);
Patch ("soundwire: qcom : use FIELD_{GET|PREP}") seems to have
accidentally removed clearing bit field while modifying the register.
Fix this by using u32p_replace_bits() to clear and set the values.

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.
