Hi Hemant,

The driver patch is from non maintainer of the driver, since you sent the patch 
I assume you are OK with it and I am adding your explicit ack:

Acked-by: Hemant Agrawal <hemant.agrawal@nxp.com>

Please let me know if the patch is not reviewed by you or you are not agree with 
the ack, I can drop the patch.

Thanks,
ferruh
