Syzbot found a warning caused by hid_submit_ctrl() submitting a control request to transfer a 0-length input report: usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType a1 (The warning message is a little difficult to understand. It means that the control request claims to be for an IN transfer but this contradicts the USB spec, which requires 0-length control transfers always to be in the OUT direction.) Now, a zero-length report isn't good for anything and there's no reason for a device to have one, but the fuzzer likes to pick out these weird edge cases. In the future, perhaps we will decide to reject 0-length reports at probe time. For now, the simplest approach for avoiding these warnings is to pretend that the report actually has length 1.

README
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.
