Okay, I just want to know if this is non-blocking comment and we can go ahead
with current version of driver.

Meanwhile my colleague Tarang is working on some features and he is planning
to send a series on top of this driver. If he takes up this comment in that
series will it be okay with you?

And also I have already sent next revision v8.
Please let me know.
