Shawn:

I am slightly confused by your phrasing. Are you:

a) saying that you dropped my patches in favor of your own that use
platform_device_add_data()

or

b) asking me to convert my patches to use platform_device_add_data()?

Just trying to figure out if any action on my part is necessary.

Thanks,
Andrey Smirnov
