Now that it's possible to capture LBR on AMD CPU from BPF at arbitrary point, there is no reason to artificially limit this feature to just sampling events. So corresponding check is removed. AFAIU, there is no correctness implications of doing this (and it was possible to bypass this check by just setting perf_event's sample_period to 1 anyways, so it doesn't guard all that much).

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.
