Subject: [PATCH] HID: roccat: Using bin-attribute->private to reduce code duplication
Date: Fri, 05 Nov 2010 18:53:59 +0100 [thread overview]
Message-ID: <1288979639.2585.17.camel@neuromancer> (raw)
In-Reply-To: <alpine.LNX.2.00.1011041418530.15851@pobox.suse.cz>
The profile number is now passed via bin-attribute->private instead
of function parameter to reduce number of functions.
