+From Grazvydas Ignotas
+
+At least xserver 1.7.4 crashes on XGetPointerControl request because of xf86-input-tslib:
+
+Program received signal SIGSEGV, Segmentation fault.
+#0  0x000355e0 in ProcGetPointerControl (client=0x4a2e58) at devices.c:2122
+#1  0x00062fa8 in Dispatch () at dispatch.c:439
+#2  0x00022444 in main (argc=4, argv=0xbeebedc4, envp=0xbeebedd8) at main.c:285
+
+This happens because ptrfeed field is not set in device structure from tslib.
+To fix this, call InitPtrFeedbackClassDeviceStruct() during DEVICE_INIT to get necessary setup done (as done in other input drivers).
