[ Upstream commitf18397ab3a] Prior to this patch was teedev_close_context() calling tee_device_put() before teedev_ctx_put() leading to teedev_ctx_release() accessing ctx->teedev just after the reference counter was decreased on the teedev. Fix this by calling teedev_ctx_put() before tee_device_put().

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.
