In e400071a805d6229223a98899e9da8c6233704a1 I added support for the
receiver that comes with the G602 device, but unfortunately I screwed up
during testing and it seems the keyboard events were actually not being
sent to userspace.
This resulted in keyboard events being broken in userspace, please
backport the fix.

The receiver uses the normal 0x01 Logitech keyboard report descriptor,
as expected, so it is just a matter of flagging it as supported.

Hans,

You added support for non unifying receivers in
74808f9115cee2bb53e7161432959f3e87b631e4, could you please test and make sure
this cause any breakage with your devices?

AFAIK, they could only break if they have a 0x01 report which is different from
kbd_descriptor.

Cheers,
Filipe Laíns

I don't have any receivers hitting the "case 7" which you are modifying,
so I don't expect to see any effects of this change on my hw.

Alright, then we should not have any other receivers that use this protocol.

Given this is a regression, could you please add proper Fixes: and Cc: 
stable tags?

Thank you,

Done :)
Sorry about that, I am not yet familiarized with all steps of the workflow.
