Check to see if the hwirq is already associated with another virq on this IRQ domain. If so, then disassociate it before associating the hwirq with the new virq. This is a temporary hack that is needed in order to not break git bisect for existing boards. The next patch in this series converts ssbi-gpio to be a hierarchical IRQ chip, then there are several patches to update all of the device tree files, and finally this patch will be reverted within the same patch series. IRQs for ssbi-gpio are all initially setup without an IRQ hierarchy this driver is probed due to the interrupts property in device tree. Once ssbi-gpio is converted to be a hierarchical IRQ chip in the next patch, existing users of gpio[d]_to_irq() will call pmic_gpio_to_irq(), and that will use the new IRQ chip code in ssbi-gpio that sets up the IRQ in an IRQ hierarchy. The hwirq is now associated with two Linux virqs and interrupts will not work as expected. This patch corrects that issue. This change was tested on an APQ8060 DragonBoard.

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.
