According to the implementation of read_poll_timeout_atomic, if the delay time is 0, it will only use a simple loop based on timeout_us to decrement the count. Therefore, the final timeout time will differ significantly from the setted timteout time. So, here we set a specific delay time to ensure that the calculation of the timeout duration is accurate.

Applied, thanks!
