ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq
in data->chip_data.

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.
