[ Upstream commit3a9ef3e11c] When a QMI handle is initialized, an array of message handler structures is provided, defining how any received message should be handled based on its type and message ID. The QMI core code traverses this array when a message arrives and calls the function associated with the (type, msg_id) found in the array. The array is supposed to be terminated with an empty (all zero) entry though. Without it, an unsupported message will cause the QMI core code to go past the end of the array. Fix this bug, by properly terminating the message handler arrays provided when QMI handles are set up by the IPA driver.

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.
