The DS4 in BT mode sends initial input reports through report 1, which is described in the HID report descriptors. When activated after sending a certain feature report, the device uses report 17. Currently the hid-sony driver fixes up the BT HID report descriptors, so the HID layer can manage input reports for report 17. We think it is best to eliminate this fixup and do the handling ourselves, which is what this patch does. The main motivation is that there are various users of DS4 through hidraw, including various cross-platform applications/games, which have their own HID parsing across Linux/Win/OSX. Due to the fixup the descriptors differ, which is causing pain for many developers including major game publishers (who reached out privately). Without the fixup, the Windows titles also have a fighting chance for working on Wine, which provides HID support now. Overall it felt best because of these reasons to remove the fixup.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
