The IRQCHIP_PLATFORM_DRIVER macros can be used to convert OF irqchip drivers to platform drivers but currently reuse the OF init callback prototype that only takes OF nodes as arguments. This forces drivers to do reverse lookups of their struct devices during probe if they need them for things like dev_printk() and device managed resources. Half of the drivers doing reverse lookups also currently fail to release the additional reference taken during the lookup, while other drivers have had the reference leak plugged in various ways (e.g. using non-intuitive cleanup constructs which still confuse static checkers). Switch to using a probe callback that takes a platform device as its first argument to simplify drivers and plug the remaining (mostly benign) reference leaks.

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.
