Should have phrased that differently; versioning modules individually
does not make much sense when we already have a kernel version which is
tied to the driver code in question and which *does* get updated as new
kernels are released (unlike these module version defines, which tend to
stay unchanged).

For USB, we've dropped module versioning entirely and push back whenever
someone proposes to add it back. Other subsystems and particularly old
drivers may still have these macros of course.

In this case, the pn533 driver (and its interface drivers) is one of only
three NFC drivers which have MODULE_VERSION, but maybe it makes sense to
keep it in, if only for consistency with the other pn533 components.

Thanks,
