Hi,

For IIO please put the change log below the ---
A few areas of the kernel do this differently but we are consistent
in using link tags (generated when I apply the patch) to give
access to change logs rather than having them stored for ever
in the main git log.

You haven't addressed my request in reply to previous posting
to use device_get_match_data() and switch to the generic
properties interfaces. I'd rather see that done in one step
then going via this cleanup.

Thanks,

Jonathan
