Hello Emil,
thanks for your effort.

IMHO you should better rename the function because now it doesn't only
allocate the device, but also registers it.
Also I doubt that it's OK to call dma_declare_coherent_memory after the
device is added. In this case maybe extend
platform_device_register_full? And also add a warning to
dma_declare_coherent_memory if it is called for an already added device?
(Added a few people to Cc: that might be able to comment this. I don't
even know if there is a reliable way to check if a device is already
added.)
Best regards
Uwe
