HID: multitouch: support PixArt optical touch screen
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[] Signed-off-by: Aaron Tian <aaron_tian@pixart.com.tw> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
