I'm thinking more like:

	error = firmware_open("cz", ..., &handle);

	...

	error = firmware_read(handle, offset, buf, buflen);

	...

	error = firmware_close(handle);

Driver allocates and frees its own buffers.  Perhaps we provide  
firmware_*() routines for buffer management (pageable vs. non- 
pageable memory, etc.)
