This description doesn't clearly convey the intention of the patches. Please
take time to write the cover letter describing what the patches do and how
they solve a problem.

If possible, do mention the platform on which the patches were tested.

And please avoid using Qualcomm specific acronymns such as CW as it only makes
sense to limited amount of people who has access to technical documents.

Thanks,
Mani
