Due to firmware bugs on the Q6 the hardware watchdog irq can be triggered multiple times. As the remoteproc framework schedules work items for the recovery process, if the other threads do not get a chance to run before recovery is completed the proceeding threads will see the state of the remoteproc as running and kill the remoteproc while it is running. This can result in various SMMU and NOC errors. This change sets the state of the remoteproc to offline whenever a watchdog irq is received.

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.
