This patch fixes crash after resuming from hibernation. The issue occurs when mhi stack is builtin and so part of the 'restore-kernel', causing the device to be resumed from 'restored kernel' with a no more valid context (memory mappings etc...) and leading to spurious crashes. This patch fixes the issue by implementing proper freeze/restore callbacks.

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.
