Fork of Freescale Linux kernel for reMarkable2 https://github.com/Freescale/linux-fslc

The irq_domain structure has an host_data pointer that just stores private data. It is meant to not be touched by the IRQ core. However, when it comes to MSI, the MSI layer adds its own private data there with a structure that also has a host_data pointer. Because this IRQ domain is an MSI domain, to access private data we should do a d->host_data->host_data, also wrapped as 'platform_msi_get_host_data()'. This bug was lying there silently because the 'icu' structure retrieved this way was just called by dev_err(), only producing a '(NULL device *):' output on the console.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
