Hi Greg,

could you point me to an example in the kernel tree where this is done
correctly for a platform device?

I had a look at

http://kroah.com/log/blog/2013/06/26/how-to-create-a-sysfs-file-correctly/

but I couldn't figure out how to create device attributes in a simple
platform driver that binds to a platform device.

Thanks a lot for your help,

   Martin
