John Keeping c0b28a0421 usb: gadget: f_hid: fix SuperSpeed descriptors
commit 7f58b4148e upstream.

When adding dynamic configuration for bInterval, the value was removed
from the static SuperSpeed endpoint descriptors but was not set from the
configured value in hidg_bind().  Thus at SuperSpeed the interrupt
endpoints have bInterval as zero which is not valid per the USB
specification.

Add the missing setting for SuperSpeed endpoints.

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.
