Make it possible to load lirc program type with just CAP_BPF. There is nothing exceptional about lirc programs that means they require SYS_CAP_ADMIN. In order to attach or detach a lirc program type you need permission to open /dev/lirc0; if you have permission to do that, you can alter all sorts of lirc receiving options. Changing the IR protocol decoder is no different. Right now on a typical distribution /dev/lirc devices are only read/write by root. Ideally we would make them group read/write like other devices so that local users can use them without becoming root.

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.
