This type of change needs to be tested before it can be merged.

Thank you for feedback.
I understand that this type of change should be tested due to its impact
on time-sensitive behavior.
However, I currently don't have access to any device that uses this
driver.
Please let me know how you'd suggest proceeding in this case.

Regards,
Kisub Choe.

Just leave it as-is until someone who has the hardware can test it.
