The MODULE_DEVICE_TABLE() macro already checks for MODULE defined,
so the extra check here is not necessary.

I don't see any reply to James' comment that these changes result in
static struct definitions that are unused, which should result in
complaints by the compiler like:
    warning: 'dptids' defined by not used [-Wunused-variable]

As James pointed out, this will result in warning from compiler about
unused variable. Please address that first.

I've missed that mail :(

hmm, seems that const is missing on dptids ... I'll test that and
repost fixed vrsion.
