From 95dd3b30ced3ee740e5dd92fc44515a5a6a350d4 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 19 Mar 2010 22:18:15 -0700 Subject: Input: wacom - get rid of wacom_combo structure Now that we moved input device from struct wacom to struct wacom_wac, presence of wacom_combo just complicats things for no good reason. Let's get rid of it and simply pass URB length to wacom_wac_irq().
