From 14a057f80f0c4d45a9e68009f8bcb6b246e87ca0 Mon Sep 17 00:00:00 2001 From: Stefan Achatz Date: Fri, 26 Nov 2010 19:57:38 +0000 Subject: HID: roccat: reduce number of functions in kone and pyra drivers The profile number is now passed via bin_attribute->private instead of function parameter to reduce number of functions.
