    Subject[PATCH 4.12 37/99] ALSA: usb-audio: Add delay quirk for H650e/Jabra 550a USB headsets
    Date
    4.12-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Joakim Tjernlund <joakim.tjernlund@infinera.com>

    commit 07b3b5e9ed807a0d2077319b8e43a42e941db818 upstream.

    These headsets reports a lot of: cannot set freq 44100 to ep 0x81
    and need a small delay between sample rate settings, just like
    Zoom R16/24. Add both headsets to the Zoom R16/24 quirk for
    a 1 ms delay between control msgs.
