Currently the reset handler was always called to deassert the reset line because assert the line was done during probe. Now if we want to support pm by turn of the supply we need to call this routine twice and the i2c_lock_bus is done twice too. To simplify that we can drop the state and just do a reset in one go. So a future pm operation don't need to lock the i2c bus twice.

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.
