commite72455b898upstream. Fix for non-working buttons on knock-off USB dongles for Sony controllers. These USB dongles are used to connect older Sony DA/DS1/DS2 controllers via USB and are common on Amazon, AliExpress, etc. Without the patch, the square, X, and circle buttons do not function. These dongles used to work prior to kernel 4.10 but removing the global DS3 report fixup in commite19a267b99("HID: sony: DS3 comply to Linux gamepad spec") exposed the problem. Many people reported the problem on the Ubuntu forums and are working around the problem by falling back to the 4.9 hid-sony driver. The problem stems from these dongles incorrectly reporting their button count as 13 instead of 16. This patch fixes up the report descriptor by changing the button report count to 16 and removing 3 padding bits.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
