Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory that lie beyond the end of the endpoint array should a malicious device lack the expected endpoints.

Touch ID for dual touch must be 0 or 1. According to the actual Neonode nine byte touch coordinate coding, the state is transported in the lower nibble and the touch ID in the higher nibble of payload byte five.

Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.

The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.
