and the line above is guarded by:

#ifdef CONFIG_MTD_NAND_MUSEUM_IDS

which is default off.

>From Kconfig:

config MTD_NAND_MUSEUM_IDS
        bool "Enable chip ids for obsolete ancient NAND devices"
        depends on MTD_NAND
        default n
        help
          Enable this option only when your board has first generation
          NAND chips (page size 256 byte, erase size 4-8KiB). The IDs
          of these chips were reused by later, larger chips.            

So there is no bug at all.
