Takashi Iwai 116e79c679 usb: gadget: midi2: Fix MIDI2 IN EP max packet size
The EP-IN of MIDI2 (altset 1) wasn't initialized in
f_midi2_create_usb_configs() as it's an INT EP unlike others BULK
EPs.  But this leaves rather the max packet size unchanged no matter
which speed is used, resulting in the very slow access.
And the wMaxPacketSize values set there look legit for INT EPs, so
let's initialize the MIDI2 EP-IN there for achieving the equivalent
speed as well.

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.
