3.2.60-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: AceLan Kao <acelan.kao@xxxxxxxxxxxxx> commit 8171a67d587a09e14a4949a81e070345fedcf410 upstream. BugLink: http://bugs.launchpad.net/bugs/1180881 Synaptics large touchscreen doesn't support some of the report request while initializing. The unspoorted request will make the device unreachable, and will lead to the following usb_submit_urb() function call timeout. So, add the IDs into HID_QUIRK_NO_INIT_REPORTS quirk.
