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. Signed-off-by: Jason Gerecke <jason.gerecke@wacom.com> --- drivers/hid/wacom_sys.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
