AVStrMiniPinReset routine

An AVStream minidriver's AVStrMiniPinReset routine is called when a KSPIN structure's reset state is changed due to the arrival of an IOCTL_KS_RESET_STATE device control. This routine is also called when the queue associated with the given pin is flushed. This routine is only called on pin-centric pins.

void AVStrMiniPinReset(
  _In_ PKSPIN Pin
