[ Upstream commit9d11af8b06] Make __qcom_scm_is_call_available() return bool instead of int. The function has "is" in the name, so it should return a bool to indicate the truth of the call being available. Unfortunately, it can return a number < 0 which also looks "true", but not all callers expect that and thus they think a call is available when really the check to see if the call is available failed to figure it 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.
