The theory is that the so called workaround in pwr_reg_rdwr() is the actual reader of the data in 32-bit chunks. For some reason the 8-bit IO won't fail after that. Replace the workaround by using 32-bit IO explicitly and then memcpy() as much data as was requested by the user. The same approach is already in use in intel_scu_ipc_dev_command_with_size().

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.
