Subject: [PATCH 168/806] HID: hid-bigbenff: driver for BigBen Interactive
PS3OFMINIPAD gamepad
commit 256a90ed9e46b270bbc4e15ef05216ff049c3721 upstream.
This is a driver to fix input mapping and add LED & force feedback
support for the "BigBen Interactive Kid-friendly Wired Controller
PS3OFMINIPAD SONY" gamepad with USB id 146b:0902. It was originally
sold as a PS3 accessory and makes a very nice gamepad for Retropie.
