This commit introduces the Guitar Hero Live driver which adds support
for the PS3 and Wii U dongles.
These dongles require a "magic" USB control message [1] to be sent
approximately every 10 seconds otherwise the dongle will not report
events where the strumbar is hit while a fret is being held.
Also, inspired by a patch sent on linux-input by Sanjay Govind [2], the
accelerometer is mapped to ABS_RY for tilt.
Interestingly, the Wii U and PS3 dongles share the same VID and PID.

Would it make more sense (with respect to how we are structuring/naming
the hid drivers) to incorporate this into hid-sony (irrespective of
currently ongoing discussions about actually splitting that driver :) )?

So if one of the allocations above succeeds and a subsequent one fails,
you're going to try re-allocate all of them next time again, leaking the
ones that previously succeeded, right?

I think it would be most appropriate, yes.
Note that there are 3 other dongles out there:
- the xbox360 dongle does not need any special treatment, it just
works with hid-generic;
- the ps4 dongle obviously makes sense to go into hid-sony (although
no one has reversed engineered that one (yet));
- the xboxone dongle: that's an unknown one to me. I don't have any
information about that one unfortunately and do not own one.
I wrote this as a separate hid driver as I saw that email [1] from
Roderick Colenbrander in which he expressed a preference for a
seperate driver in cases where the device is not from Sony proper.

I attempted to avoid such a case. IIUC there are 4 possible scenarios
tied to those 3 allocs (cr, databuf, and urb):
1) alloc of cr fails. nothing to be freed, we reschedule;
2) alloc of cr succeeds, alloc of databuf fails. we free cr and we reschedule;
3) allocs of cr and databuf succeed, alloc of urb fails. we free cr
and databuf, and we reschedule;
4) all allocs succeed, we submit the urb, and free urb. once the
control packet is sent, the callback is called and we free cr and
databuf.
Am I missing something? It's VERY possible that I am as this is my
first patch and I wrote this by looking at other peoples' code. The
only thing that comes to mind is if poke is called again before the
control packet actually gets sent (and the callback called), in which
case I'm not sure what would happen. But with a poke interval of 10
seconds, is that probability close enough to 0 to be ignored?
Thanks again for your valuable input, :-)

Yeah, but before that happens, I think we should just continue with status
quo, meaning putting the support into hid-sony, if noone has any
objections.

No, I probably didn't have my first coffee of the day when looking at your
patch, sorry.
Still, the way it tries to allocate the buffers is sub-optimal, as if
either (not necessarily the first one) fails, it retries the next
iteration with attempting to allocate from scratch.
If the system really is in tight memory condition, it'd make more sense to
keep the ones for which the allocation succeeded already allocated, and
retry only the failed one(s).

Hi Pascal,
thanks for fixing the previous version. This one looks good to me, I just
have one remaining question -- why do we need both quirks here? Given the
particular VID/PID gets both of them set anyway (and only that VID/PID),
and the code is shared, what is the point of consuming the extra bit?
Thanks,

Yeah, let's extend this only when really needed.

Please do, thanks. I'll merge that one, I promise :) Sorry for not
having catched this in v1 already.

Apologies for the resend. I had not realized that gmail's app for
smartphones didn't really support plaintext.

No worries, will do.
Thanks again!

This commit adds support for the Guitar Hero Live PS3 and Wii U dongles.
These dongles require a "magic" USB control message [1] to be sent
approximately every 10 seconds otherwise the dongle will not report
events where the strumbar is hit while a fret is being held.
Also, inspired by a patch sent on linux-input by Sanjay Govind [2], the
accelerometer is mapped to ABS_RY for tilt.
Interestingly, the Wii U and PS3 dongles share the same VID and PID.

Changes in v3:
* Only use one quirk as for now only the PS3/WiiU dongle is supported.
Changes in v2:
* Patches hid-sony instead of creating a new driver
* Changed memory allocation scheme in case of fail
