seg fault when disabling callbacks

[PerryC]

Passing NULL as the 4th param XlineConfigureChangedInputsCallback() to disable the callback is causing a segmentation fault on my wheezy build raspi (3.1.9+ #272 PREEMPT). Even the sample app iodemo does this for me so hopefully easy enough to reproduce.

Perry,

The function ConfigureChangedInputsCallback() takes three parameters, so I am guessing you are placing NULL into parameter three the callback function pointer. If this is the case NULL will be called causing the SEG FAULT. You can always pass a empty function pointer that does nothing.
