No, it won't.

Currently atmel_nand uses its of_device_id for just the of_match_table,
while pxa3xx-nand uses the pxa3xx_nand_dt_ids for more than just that,
as a paramater for of_match_device().

The latter prevents the warning by having an actual dummy-inlined
implementation for the !OF case.

I'll answer about the atmel_nand in the respective patch.
