[PATCH 1/2] HID: kye: Add report fixup for Genius Manticore Keyboard

[Benjamin Tissoires]

Genius Manticore Keyboard presents the same problem in its report
descriptors than Genius Gila Gaming Mouse and Genius Imperator Keyboard.
Use the same fixup.

[PATCH 2/2] HID: kye: fix unresponsive keyboard

[Benjamin Tissoires]

The manticore keyboard requires that all usb EP are opened at least
once to be fully functional. The third EP forwards to the user space
some vendor specific information about the keyboard state, but are useless
currently for the kernel.

Opening them and closing them makes the keyboard responsive again.

Hi Jiri,

well, this one was a long shot as I do not have the hardware to actually
spot the exact call which enables the keyboard. Adam told me that just
opening and closing once all the /dev/hidrawX attached to the keyboard makes
the keyboard functional, so, here is the kernel version of this.
Anyway, it just works, so I think we can take this one as well.

Cheers,
Benjamin

Man, this is ugly :)

What can we do anyway. Applied, thanks.
