UPSTREAM: HID: sony: Fix for broken buttons on DS3 USB dongles
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 commit e19a267b9987 ("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.
