For some scenarios like controller suspend and resume, mhi_destroy_device() will get called without mhi_unregister_controller(). In that case, the references to the mhi_dev created for the channels will not be dropped but the channels will be destroyed as per the spec. This will cause issue during resume as the channels will not be created due to the fact that mhi_dev is not NULL. Hence, this change decrements the refcount for mhi_dev in mhi_destroy_device() for concerned channels and also sets mhi_dev to NULL in release_device().

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.
