[PATCH 2/5] staging: bcm2835-camera: Fix integer underrun in port_parameter_get

2017-03-17 Thread Michael Zoran
Fix port_paremeter_get function blindly subtracts 8 from a reply size without checking that the size is at lest 8 bytes. This can casue a large buffer to be copied since the size is unsigned. Add a WARN_ON, and also add min and max conditions to the size of the data that is copied.
