When getting unexpected data while waiting for an acknowledgement it does not matter what command phase is currently executed, and ps2_handle_ack() should indicate that no further processing is needed for the received data byte. Remove PS2_FLAG_ACK_CMD and associated handling. Note that while it is possible to make ps2_handle_ack (and ps2_handle_repsonse) return void, it will be done when the code will be converted to common PS/2 interrupt handler later.

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.
