Linux kernel source tree
6ec3185fbc
Due to what seem to be a bug with variant version returned by some
firmwares the code may set hdev->classify_pkt_type with
btintel_classify_pkt_type when in fact the controller doesn't even
support ISO channels feature but may use the handle range expected from
a controllers that does causing the packets to be reclassified as ISO
causing several bugs.
To fix the above btintel_classify_pkt_type will attempt to check if the
controller really supports ISO channels and in case it doesn't don't
reclassify even if the handle range is considered to be ISO, this is
considered safer than trying to fix the specific controller/firmware
version as that could change over time and causing similar problems in
the future.

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.
