Ilpo Järvinen c22b4f159b wifi: rtlwifi: Remove bogus and dangerous ASPM disable/enable code commit b3943b3c2971444364e03224cfc828c5789deada upstream. Ever since introduction in the commit `0c8173385e` ("rtl8192ce: Add new driver") the rtlwifi code has, according to comments, attempted to disable/enable ASPM of the upstream bridge by writing into its LNKCTL register. However, the code has never been correct because it performs the writes to the device instead of the upstream bridge. Worse yet, the offset where the PCIe capabilities reside is derived from the offset of the upstream bridge. As a result, the write will use an offset on the device that does not relate to the LNKCTL register making the ASPM disable/enable code outright dangerous. Because of those problems, there is no indication that the driver needs disable/enable ASPM on the upstream bridge. As the Capabilities offset is not correctly calculated for the write to target device's LNKCTL register, the code is not disabling/enabling device's ASPM either. Therefore, just remove the upstream bridge related ASPM disable/enable code entirely. The upstream bridge related ASPM code was the only user of the struct mp_adapter members num4bytes, pcibridge_pciehdr_offset, and pcibridge_linkctrlreg so those are removed as well. Note: This change does not remove the code related to changing the device's ASPM on purpose (which is independent of this flawed code related to upstream bridge's ASPM).

README

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.
