Subject: [PATCH 3.12 008/103] HID: usbhid: quirk for CY-TM75 75 inch Touch Overlay

From: Yufeng Shen <miletus@...omium.org>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 29191039e21f66e204acffed63c486674a1918bd upstream.

There is timeout error during initialization:
kernel: [   11.733104] hid-multitouch 0003:1870:0110.0001: usb_submit_urb(ctrl) failed: -1
kernel: [   11.734093] hid-multitouch 0003:1870:0110.0001: timeout initializing reports

Adding quirk HID_QUIRK_NO_INIT_REPORTS can solve the problem.
