Can't the entry be shared for both platform_device_id and of_device_id?
Only one of them can be valid at the same time, right?

Ideally, all xxx_device_id look like

struct xxx_device_id {
... /* bus-specific ID information */
kernel_ulong_t driver_data;
};

This may be formalized in some way, using a base class, but thay may
require reordering the fields, like:

struct base_device_id {
kernel_ulong_t driver_data;
long id[0];
};
