1. Check if gpio pin number is in valid range to prevent from get invalid
pointer 'desc' in the following code:
desc = (const struct mtk_pin_desc *)&hw->soc->pins[gpio];
2. Improve mtk_hw_pin_field_lookup()
2.1 Modify mtk_hw_pin_field_lookup() to use binary search for accelerating
search.
2.2 Correct message after the following check fail:
if (hw->soc->reg_cal && hw->soc->reg_cal[field].range) {
rc = &hw->soc->reg_cal[field];
The original message is:
"Not support field %d for pin %d (%s)\n"
However, the check is on soc chip level, not on pin level yet.
So the message is corrected as:
"Not support field %d for this soc\n"

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.
