commit 37b9dd0d114a0e38c502695e30f55a74fb0c37d0 upstream.
Drop the check on the maximum transfer length in Raw Gadget for both
control and non-control transfers.
Limiting the transfer length causes a problem with emulating USB devices
whose full configuration descriptor exceeds PAGE_SIZE in length.
Overall, there does not appear to be any reason to enforce any kind of
transfer length limit on the Raw Gadget side for either control or
non-control transfers, so let's just drop the related check.

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.
