Take f_midi_bind() for example, when composite layer call it, it will allocate hs descriptor by calling gadget_is_dualspeed() API to check gadget max support speed capability, but most other gadget function didn't do like this. To follow other function drivers, it is safe to remove the check which mean support all possible link speed by default in function driver. Similar change apply to midi2 and uvc. Also in midi and midi2, as there is no descriptor difference between super speed and super speed plus, follow other gadget function drivers, do not allocate descriptor for super speed plus, composite layer will handle it properly.

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.
