The existing check_and_ack() function had unnecessary complexity. The logic could be streamlined to improve code readability and maintainability. The command update register needs to be updated in order to acknowledge the platform notification through type 4 channel. So it can be done unconditionally. Currently it is complicated just to make use of pcc_send_data() which also executes the same updation. In order to simplify, let us just ring the doorbell directly from check_and_ack() instead of calling into pcc_send_data(). While at it, rename it into pcc_chan_check_and_ack() to maintain consistency in the driver.

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 reStructuredText 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.
