Message-ID<tPCaB-2s3-1@gated-at.bofh.it>
When plugging in an Oculus Rift CV1 HMD, it takes a long time until the hidraw
devices appear, specifically two control transfers time out querying the HID
report descriptors:

    $ echo 1 > /sys/module/hid/parameters/debug

These timeouts disappear when setting HID_QUIRK_NO_INIT_REPORTS. The hidraw
devices appear quickly and are functional.

2 things:
- the 2 patches should be squashed together. There is no point having a
  single patch for just 2 defines not used anywhere else.
- I believe you don't even need this quirk in the development version of
  the hid tree. Would you mind trying a plain v4.12-rcX and report if
  you still need the quirk?

Cheers,
Benjamin
