There are several issues with the function that implements writing to the filter_low_pass_3db_frequency property: - The sinc3 factor should be 0.272 not 0.262 (this is fixed for the reading side in the previous patch). - For freq > 1 the if condition is always true so the sinc4 filter is hardly ever chosen. - In the nearly always taken if branch the filter is set to sinc3, but the frequency is set for sinc4. (And vice versa in the else branch.) This is broken enough to justify the claim that there isn't any serious user. Also it it counter-intuitive that setting the 3db frequency modifies the sample frequency and the filter type. So drop the ability to write that property.

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.
