commit0178f9d0f6upstream. Do not tear down the system when getting invalid status from a TPM chip. This can happen when panic-on-warn is used. Instead, introduce TPM_TIS_INVALID_STATUS bitflag and use it to trigger once the error reporting per chip. In addition, print out the value of TPM_STS for improved forensics.

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.
