Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
greybus_hd_type, greybus_module_type, greybus_interface_type,
greybus_control_type, greybus_bundle_type and greybus_svc_type variables to
be constant structures as well, placing it into read-only memory which can
not be modified at runtime.

This looks good to me.  Assuming it compiles cleanly:

Reviewed-by: Alex Elder <elder@linaro.org>

On another subject:

Johan might disagree, but I think it would be nice to make
the definitions of the Greybus device types as static (private)
and make the is_gb_host_device() etc. functions real functions
rather than static inlines in <linux/greybus.h>.

It turns out that all of the is_gb_*() functions are called only
from drivers/greybus/core.c; they could all be moved there rather
than advertising them in <linux/greybus.h>.

I guess it depends whether they would be used somewhere else in the
future. Perhaps it was left there with that intention when it was first
being developed? I agree, though. Will happily send a patch with this if
desired.

Let's clean the code up for what we have today.  If it's needed in the
future, we can move the structures then.

Sounds good to me, will send a v2 then!

I might be misinterpreting Greg's response; I *think* he
agrees with my suggestion.

In any case, please do *not* send v2 with the purpose of
including my suggestion.

If you send a v2, keep it focused on this original patch.
You can then implement the other suggestion as a follow-on
patch (or series).

That's what I thought too.

Indeed, this one is good as is but I thought of converting it into a
series so that they can be taken with no dependency on this one. So it
would look like:

Patch 1: move "is_gb_*()" into drivers/greybus/core.c
Patch 2: move "device_type greybus_*" into drivers/greybus/core.c
Patch 3: make "device_type greybus_*" const

But you're right. I could simply send 1 and 2 after this one has been
applied. If I were to send them separately, how would I communicate that
there's a dependency? Something like:

---
This series depends on [1].
[1]: lore://link-to-this-patch 

?

Thanks and sorry for the noobishness

Sorry, this made no sense!
