On older Kernels (prior to 4.15) irqreturn_t and devm_request_threaded_irq is not defined when compiling adv7604.c. It seems more recent Kernels include it via another header which is included by adv7604.c. Now we include linux/interrupt.h explicitly to get the type also defined for Kernels prior to 4.15.

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.
