Viken Dadhaniya 2a47da1cd8 slimbus: qcom-ngd-ctrl: Add timeout for wait operation 
commit 98241a774d upstream.

In current driver qcom_slim_ngd_up_worker() indefinitely
waiting for ctrl->qmi_up completion object. This is
resulting in workqueue lockup on Kthread.

Added wait_for_completion_interruptible_timeout to
allow the thread to wait for specific timeout period and
bail out instead waiting infinitely.

README 

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.
