[PATCH 1/3] HID: roccat: Reducing number of functions in kone and pyra drivers

Stefan Achatz
2010-11-06T18:51:58Z

The profile number is now passed via bin_attribute->private instead
of function parameter to reduce number of functions.
This patch does for kone and pyra what a previous patch did for
koneplus.
