This does seem to be real.
As of 99c18ce580c6 ("cramfs: direct memory access support") cramfs
seems to require MTD, but that's not expressed in the Kconfig.
Oddly, _some_ of the mtd functions are protected with
if (IS_ENABLED(CCONFIG_CRAMFS_MTD) ..)
but cramfs_mtd_fill_super() is not.
It is only *used* if CONFIG_CRAMFS_MTD is enabled (the call to
mount_mtd(.., cramfs_mtd_fill_super) is conditional, but..
