Yazen Ghannam 55ea884c0d x86/mce: Don't remove sysfs if thresholding sysfs init fails
commit 4c113a5b28 upstream.

Currently, the MCE subsystem sysfs interface will be removed if the
thresholding sysfs interface fails to be created. A common failure is due to
new MCA bank types that are not recognized and don't have a short name set.

The MCA thresholding feature is optional and should not break the common MCE
sysfs interface. Also, new MCA bank types are occasionally introduced, and
updates will be needed to recognize them. But likewise, this should not break
the common sysfs interface.

Keep the MCE sysfs interface regardless of the status of the thresholding
sysfs interface.

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.
