irq_create_fwspec_mapping() can fail, returning 0 as parent_virq. In this case vint_desc is going to be NULL in ti_sci_inta_alloc_irq() which will cause NULL pointer dereference. Also note that irq_create_fwspec_mapping() returns 'unsigned int' so the check '<=' was wrong. Use -EINVAL if irq_create_fwspec_mapping() returned with 0.

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.
