Commitcc0cc23bab("powerpc/xive: Untangle xive from child interrupt controller drivers") changed xive_irq_data to be stashed to chip_data instead of handler_data. However, multiple places are still attempting to read xive_irq_data from handler_data and get a NULL pointer deference bug. Update them to read xive_irq_data from chip_data. Non-XIVE files which touch xive_irq_data seem quite strange to me, especially the ocxl driver. I think there ought to be an alternative platform-independent solution, instead of touching XIVE's data directly. Therefore, I think this whole thing should be cleaned up. But perhaps I just misunderstand something. In any case, this cleanup would not be trivial; for now, just get things working again.

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 reStructuredText 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.
