From f2209d4aefac246772152c5294af49f2800f646b Mon Sep 17 00:00:00 2001 From: Jason Gerecke Date: Wed, 19 Oct 2016 18:03:41 -0700 Subject: [PATCH] HID: wacom: generic: Strip off excessive name prefixing The product name received from the string descriptor in the new MobileStudio Pro line of tablets begins with "Wacom", which leads to unnecessary visual noise in the device name when appended to the vendor name which also includes "Wacom". Look for and fix cases like this.
