Subject: HID: kye: Add report fixup for Genius Gila Gaming mouse
Genius Gila Gaming Mouse presents an obviously wrong report descriptor.
the Consumer control (report ID 3) is the following:
0x05, 0x0c, // Usage Page (Consumer Devices) 105
0x09, 0x01, // Usage (Consumer Control) 107
0xa1, 0x01, // Collection (Application) 109
0x85, 0x03, // Report ID (3) 111
0x19, 0x00, // Usage Minimum (0) 113
0x2a, 0xff, 0x7f, // Usage Maximum (32767) 115
0x15, 0x00, // Logical Minimum (0) 118
0x26, 0xff, 0x7f, // Logical Maximum (32767) 120
0x75, 0x10, // Report Size (16) 123
0x95, 0x03, // Report Count (3) 125
0x81, 0x00, // Input (Data,Arr,Abs) 127
0x75, 0x08, // Report Size (8) 129
0x95, 0x01, // Report Count (1) 131
0x81, 0x01, // Input (Cnst,Arr,Abs) 133
0xc0, // End Collection 135
So the first input whithin this report has a count of 3 but a usage range
of 32768. So this value is obviously wrong as it should not be greater than
the report count.
