Module: wine
Branch: master
Commit: 947e6ee5b43cda0f8b610567886286a26caf375c

dinput: Wait for the internal thread to complete unacquiring.

Otherwise we may close HID read event before it has finished removing it
from the wait handles, causing MsgWaitForMultipleObjectsEx to return an
error and terminate.
