From: Stefan Achatz Date: Fri, 26 Nov 2010 19:57:38 +0000 (+0000) Subject: HID: roccat: reduce number of functions in kone and pyra drivers X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=14a057f80f0c4d45a9e68009f8bcb6b246e87ca0;p=linux-beck.git 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.
