Merge branch 'for-4.16/hid-quirks-cleanup/_base' into for-linus

Browse Source 
This series from Benjamin Tissoires finally removes one of the big PITAs
in the hid-core, which is the absolute need of having added all the new
device IDs into the horrid hid_have_special_driver[]

---help---
Support for Jabra USB HID devices.
Prevents mapping of vendor defined HID usages to input events. Without
this driver HID reports from Jabra devices may incorrectly be seen as
mouse button events.
Say M here if you may ever plug in a Jabra USB device.
