commitf8914a1462upstream. This patch restores the old behavior that read the chip_id on the QCA988x before resetting the chip. This needs to be done in this order since the unsupported QCA988x AR1A chips fall off the bus when resetted. Otherwise the next MMIO Op after the reset causes a BUS ERROR and panic.

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.
