Subject: [PATCH] hid: add QUIRK_HIDDEV for Belkin Flip KVM

From: Daniel P. Engel <dengel@...rceharvest.com>

Add HID_QUIRK_HIDDEV for the Belkin Flip USB KVM to the hid-core
blacklist table. The Belkin Flip USB KVM provides for software
control of switching via a HID class interface. It overloads
three HID LED usages, two of which aren't mapped in the ev_dev input
subsection, and which it doesn't make sense to map. In order to
force the creation of a hiddev device for controlling
the Flip, this quirk flag is needed.
