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
