There is no pull-up resistor at IRQ line where it connects from the codec to SoC. When booting, the signal of IRQ pin will keep low which makes the SoC invoke the ISR repeatedly because the IRQ is registered trigger low. It will not stop until the codec sets up the interruption and pulls the signal high. In the patch, nau8825 will internally pull the signal to high at booting in case the fake interrupts happen.

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.
