1.Refine mtk_pinconf_get():
Use only one occurrence of return at end of this function.
2.Refine mtk_pinconf_set():
2.1 Use only one occurrence of return at end of this function.
2.2 Modify case of PIN_CONFIG_INPUT_ENABLE -
2.2.1
Regard all non-zero setting value as enable, instead of always enable.
2.2.2
Remove check of ies_present flag and always invoke mtk_hw_set_value()
since mtk_hw_pin_field_lookup() invoked inside mtk_hw_set_value() has
the same effect of checking if ies control is supported.
[The rationale is that: available of a control is always checked
in mtk_hw_pin_field_lookup() and no need to add ies_present flag
specially for ies control.]
2.3 Simply code logic for case of PIN_CONFIG_INPUT_SCHMITT.
2.4 Add case for PIN_CONFIG_INPUT_SCHMITT_ENABLE and process it with the
same code for case of PIN_CONFIG_INPUT_SCHMITT.

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.
