[RFCv3,0/7] USI stylus support series

Hi,

Another update here based on received feedback. Main change compared to v2:

- Dropped patch #5 : HID: core: map USI pen style reports directly
  This is not needed anymore, as the same result can be reached by
  modifying the flags of the relevant field in rdesc. This is done now
  as part of patch #7 in the BPF code.

I also dropped one of the fixes from my test branch [1] as pointed out
by Benjamin, it is not needed if the BPF program is executed with the
modalias link.

Updated test branch can be found from [2].

If that's OK with you, I'd like to cherry-pick some patches from the
series: 1/7, 2/7 (the version from v4 because I requested changes),
4/7 and a lighter 5/7 where we don't have the MSC events we are still
discussing.

So Ideally, can you post a v4 based on top of hid.git/for-next
(without my hid-bpf changes) with those 4 patches?

Patch 3 is still up for discussion, and patches 6 and 7 are obviously RFC.

Actually, Patch 3 could be split into a part where you add the HID
usages and a part with the mapping of them. The HID usages part can be
integrated now too, and we'll have the USI mapping that would require
Dmitry's ack in a separate patch.

But if you prefer having everything in one series, that's fine by me too.

Cheers,
Benjamin
