[Why] The dce_i2c_hw code contained four funtcions that were only called in one place and did not have a clearly delineated purpose. [How] Inline these functions, keeping the same functionality. This is not a functional change. The functions disable_i2c_hw_engine and release_engine_dce_hw were pulled into their respective callers. The most interesting part of this change is the acquire functions. dce_i2c_hw_engine_acquire_engine was pulled into dce_i2c_engine_acquire_hw, and dce_i2c_engine_acquire_hw was pulled into acquire_i2c_hw_engine. Some notes to show that this change is not functional: -Failure conditions in any function resulted in a cascade of calls that ended in a 'return NULL'. Those are replaced with a direct 'return NULL'. -The variable result is the one from dce_i2c_hw_engine_acquire_engine. The boolean result used as part of return logic was removed. -As the second half of dce_i2c_hw_engine_acquire_engine is only executed if that function is returning true and therefore exiting the do-while loop in dce_i2c_engine_acquire_hw, those lines were moved outside of the loop.

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.
