You'll find it being used in drivers/base/isa.c for one. I only used it 
there because it was available and made for slightly nicer code though. 
If platform_data is going away (and assuming you wouldn't want similar 
abuse of your new system_data) it wouldn't be a problem to move the 
driver pointer to the private struct isa_dev as in the attached.
