From: Aaron Tian <aaron_tian@xxxxxxxxxxxxx>
This patch modifies hid-multitouch driver for supporting PixArt optical
touch screen.
Because of the device does not have to set initial report, we apply
"HID_QUIRK_NO_INIT_REPORTS" quirk
and add the device into hid_blacklist in drivers/hid/usbhid/hid-quirks.c.
The patch is according to commit 45e713efe2fa574b6662e7fb63fae9497c5e03d4
of Linux mainline git (3.2.0-rc4+)

v2: Fixed comments by Benjamin's suggestion.
Add MT_CLS_INRANGE_CONTACTNUMBER class.
