hid-acer kernel module

Acer keyboards e.g. in Acer SW5-012 use synaptics touchpad USB ID (06cb:2968 and 06CB:2991) and have the following issue:

The report descriptor specifies an excessively large number of usages and logical max (2^16), which is more than HID_MAX_USAGES. This prevents proper parsing of the report descriptor.
