You could eventually write this as

  static bool nmk_i2c_wait_xfer_done(struct nmk_i2c_dev *priv)
  {
	if (priv->timeout_usecs < jiffies_to_usecs(1)) {
		...

		return !wait_event_hrtimeout(...);
	}

	...
	return wait_event_timeout(...);
  }

It looks a bit cleaner to me... your choice.

Rest looks good.
