commit 92461f5d723037530c1f36cce93640770037812c upstream.
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.

We will never use packet_id before initializing it as we start with
"need_blobs == -1" and will set packet_id there.
Also use le32_to_cpu when fetching header->packet_id.

This patch adds support for the built-in multitouch sensor in the Samsung
SUR40 touchscreen device, also known as Microsoft Surface 2.0 or Microsoft
Pixelsense. Support for raw video output from the sensor as well as the
