MHI suspend/resume are symmetric and balanced procedures. If device is not in M3 state on a resume, that means something happened behind our back. In this case resume is aborted and error reported, to let the controller handle the situation. This is mainly requested for system wide suspend-resume operation in PCI context which may lead to power-down/reset of the controller which will then lose its MHI context. In such cases, PCI driver is supposed to recover and reinitialize the 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.
