Input: alps - v7: ignore new packets

	/*

	 * NEW packets are send to indicate a discontinuity in the finger

	 * coordinate reporting. Specifically a finger may have moved from

	 * slot 0 to 1 or vice versa. INPUT_MT_TRACK takes care of this for

	 * us.

	 *

	 * NEW packets have 3 problems:

	 * 1) They do not contain middle / right button info (on non clickpads)

	 *    this can be worked around by preserving the old button state

	 * 2) They do not contain an accurate fingercount, and they are

	 *    typically send when the number of fingers changes. We cannot use

	 *    the old finger count as that may mismatch with the amount of

	 *    touch coordinates we've available in the NEW packet

	 * 3) Their x data for the second touch is inaccurate leading to

	 *    a possible jump of the x coordinate by 16 units when the first

	 *    non NEW packet comes in

	 * Since problems 2 & 3 cannot be worked around, just ignore them.
