Linux kernel source tree
b28654233f
It's valid to give different protocols via multiple GTBs; e.g. a MIDI 1.0 port is embedded in a MIDI 2.0 device that talks with MIDI 2.0 protocol. However, the current driver implementation assumes only a single protocol over the whole Endpoint, and it can't handle such a scenario. This patch changes the driver's behavior to parse GTBs to accept multiple protocols. Instead of switching to the last given protocol, it adds the protocol capability bits now. Meanwhile, the default protocol is chosen by the first given protocol in GTBs. Practically seen, this should be a minor issue, as new devices should specify the protocols properly via UMP Endpoint Info messages, so this is rather just covering a corner case.

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.
