Shiju Jose b972fdba86 EDAC/ghes: Fix NULL pointer dereference in ghes_edac_register() 
After

  b9cae27728 ("EDAC/ghes: Scan the system once on driver init")

and with CONFIG_DEBUG_TEST_DRIVER_REMOVE enabled, ghes_hw.dimms becomes
a NULL pointer after the second ->probe() (aka ghes_edac_register())
which the config option causes to be called.

This happens because the static variable which holds down whether
the system has been scanned already, doesn't get reset in
ghes_edac_unregister(). Then, on the second probe, ghes_scan_system()
doesn't get to enumerate the DIMMs, leading to ghes_hw.dimms remaining
NULL.

Clear the variable and rename it to something more descriptive so that a
second probe succeeds.

 [ bp: Rewrite commit message. ]

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.
