commit f25889f931 upstream.
The following out of memory errors are seen on kexec reboot
from the optee core.
[ 0.368428] tee_bnxt_fw optee-clnt0: tee_shm_alloc failed
[ 0.368461] tee_bnxt_fw: probe of optee-clnt0 failed with error -22
tee_shm_release() is not invoked on dma shm buffer.
Implement .shutdown() method to handle the release of the buffers
correctly.

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.
