kselftest tries to read/write the default value. The default register value of playback gain is 0x1F(mute), but max gain we specified is 0x12. The range of the control is 0x0~0x12 and mute(0x1F) is only used in the driver internally. To solve the problem, implement a new callback mt6359_get_playback_volsw to report user configured volume instead of the register value. In addition, update max of "Headset Volume" to 0x12, so it can match the maximum seen on latest data sheet.

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.
