+Subject: [PATCH 168/703] 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.
