commit cc5e0f08ca2a66fc4c6984ccff74fd529e969fac upstream.

The evdev buffer isn't big enough when you get many fingers on the
device. Bump up the buffer to a reasonable size, matching what other
multitouch devices use. Without this change, events may be discarded in
the evdev buffer before they are read.
