Hey, goodie.  Can we merge the trivial one-liners into a single patch that 
fixes the issue?

Also, that "firmware_attr_data" thing should probably be marked 'const', 
no? That should make it more obvious that it's ok to share across multiple 
different firmware file, I think.

You removed everybody from the Cc: line, so I doubt Eric even sees your 
email. I added the cc's back in.
