This can be moved inside the .c-file?

I can move that.

Could we simply replace these four lines with one line:

#deifne VTPM_PROXY_IOC_NEW_DEV _IOW('t', 0x00, struct vtpm_proxy_new_dev);

Does this make it better?

I changed the magic but does it matter?

I would keep the magic at '0xa1'. The documentation is written to '0xa1' 
now and seems to be good just as any other.
