Mario Limonciello (AMD) 122c3cb563 crypto: ccp - Declare PSP dead if PSP_CMD_TEE_RING_INIT fails
[ Upstream commit 5e599d7871 ]

tee_init_ring() only declares PSP dead if the command times out.
If there is any other failure it is still considered fatal though.
Set psp_dead for other failures as well.

Fixes: 949a0c8dd3 ("crypto: ccp - Move direct access to some PSP registers out of TEE")

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.
