Stanley.Yang 601429cca9 drm/amdgpu: Skip do PCI error slot reset during RAS recovery
Why:
    The PCI error slot reset maybe triggered after inject ue to UMC multi times, this
    caused system hang.

How:
    In RAS recovery, mode-1 reset is issued from RAS fatal error handling and expected
    all the nodes in a hive to be reset. no need to issue another mode-1 during this procedure.

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.
