[ Upstream commit 2e3f0d693875db698891ffe89a18121bda5b95b8 ] Add qcom_smem_bust_hwspin_lock_by_host to enable remoteproc to bust the hwspin_lock owned by smem. In the event the remoteproc crashes unexpectedly, the remoteproc driver can invoke this API to try and bust the hwspin_lock and release the lock if still held by the remoteproc 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.
