From d07a9cba6be5c0e947afc1014b5a62182a86f1f1 Mon Sep 17 00:00:00 2001 From: Tim Cole Date: Thu, 7 May 2009 17:08:42 -0700 Subject: Input: joydev - blacklist digitizers BTN_TOUCH is not set by the wacom driver which causes it to be handled by the joydev driver while the resulting device is broken. This causes problems with applications that try to use a joystick device.

Problem is that 'gain' is passed in as signed integer. Multiplying magnitude (__u16) with gain (int) causes magnitude read as signed and results negative value (with magnitude > 0x8000). This signed integer is then divided and value, still negative, converted to 32bit unsigned integer. Finally checking combine overflow min(new+old, 0xffff) gives out 0xffff. Fix is to simply change 'gain' to unsigned int.
