From ce7169652532a95bebbf2f02cd330a4e66f171ae Mon Sep 17 00:00:00 2001 From: Stefan Achatz Date: Sun, 10 Mar 2013 12:33:02 +0100 Subject: HID: roccat: add support for IskuFX Extending isku module with one additional and one changed sysfs attr. IskuFX has larger light sysfs attr. Made the code size tolerant so both devices can be handled.
