Debugging content present in the FIFO register is tricky as when we read the FIFO register that changes the content of fifo struct which reduces number of possible ways of debugging it. Rf69 uC has the possibility of triggering certain IRQs depending on how many items are in the FIFO queue, so being able to know what's in there is an important way to troubleshoot certain problems. This patch removes the requirement of having to compile pi433 driver with DEBUG_FIFO_ACCESS set and let that be driven by printk verbositity level and/or dynamic debug config instead.

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.
