Subject: USB: gadget: Make g_hid device class conform to spec.
From: Orjan Friberg <[email protected]>
commit 33d2832ab0149a26418d360af3c444969a63fb28 upstream.
HID devices should specify this in their interface descriptors, not in the
device descriptor. This fixes a "missing hardware id" bug under Windows 7 with
a VIA VL800 (3.0) controller.
