I looked at all the patches and found that most of them do not
use the table any more, or will stop using it in the near future.
I think your work to validate the correctness of the entries
is useful, but it may be more helpful to focus on removing
all the unused tables, including those that have a
MODULE_DEVICE_TABLE() tag.
If you are planning to do more such cleanups, maybe you can
go through them one subsystem at a time and look for drivers
that have both of_device_id and i2c_device_id/platform_device_id/
spi_device_id tables. If nothing in the kernel creates a device
with the legacy string, you can then send a patch that removes
the old device ID list and at the same time makes the DT support
unconditional in case there is an #ifdef CONFIG_OF check.
If the probe() function accesses platform_data, this would also
be unused, allowing an even nicer cleanup of removing the
platofrm_data path in favor of OF properties.
