The format of tpdm's peripheral id is 1f0exx. To avoid potential conflicts in the future, update the .id_table's id to 0x001f0e00. This update will narrow down the matching range and prevent incorrect matches. For example, another component's peripheral id might be f0e00, which would incorrectly match the old id.

Please could you add "Fixes" tag for this ? You don't want an old kernel detect something else as TPDM, so this must go to stable kernels. Also, while at it, please could you intend the id and mask values with tabs, so it is easier to what exactly we are matching ? e.g,
.id = 0x001f0e00, .mask = 0x00ffff00,
Kind regards Suzuki
