It has similarities with acpi_create_platform_device().
I guess we can utilize existing code.

For sure, this particular segment is effectively same as part of
acpi_create_platform_device():

Not the same, acpi_create_platform_device() does a bit more than
copying the resources. If it indeed makes no hurt...

        list_for_each_entry(rentry, &resource_list, node)
            acpi_platform_fill_resource(adev, rentry->res,
                            &resources[count++]);
So is your idea to refactor this common segment into a helper function?

...I would go with helper.


Hi Andy,

Since the plan now is that this code is no longer going to be added to
drivers/acpi, but instead pushed to the LLDD, I am pondering whether we
should still factor out of this common code. Opinion?

I would still go with a common helper. Though, as first step, we can
make it lazy, i.e. put a comment in your code, like a todo notice (w/o
TODO word :-) ) to consider a common helper.

Fine, I was also thinking that I don't want to do this now as it could make merging the patchset more complex. For now, the ACPI change I plan creates no dependencies.

Cheers,
John
