During command status or command complete event, the controller may set ncmd=0 indicating that it is not accepting any more commands. In such a case, host holds off sending any more commands to the controller. If the controller doesn't recover from such condition, host will wait forever, until the user decides that the Bluetooth is broken and may power cycles the Bluetooth. This patch triggers the hardware error to reset the controller and driver when it gets into such state as there is no other wat out.

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.
