From 152fd6347e63d176d1f03c8d142e534a5227ef3f Mon Sep 17 00:00:00 2001 From: Nikolai Kondrashov Date: Fri, 28 Jan 2011 14:50:51 +0300 Subject: HID: rename hid-drff.c to hid-dr.c Rename drivers/hid/hid-drff.c (a DragonRise Inc. force feedback gamepad driver) to driver/hid/hid-dr.c. This prepares it for addition of support for another gamepad, without force feedback.
