On 6.14.x i have a little more, info...

I've got all the CRYPTO stuff enabled, pretty sure that comes from
CONFIG_CRYPTO_MANAGER

CONFIG_CRYPTO_MANAGER=y
CONFIG_CRYPTO_MANAGER2=y
CONFIG_CRYPTO_USER=y
# CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
# CONFIG_CRYPTO_MANAGER_EXTRA_TESTS is not set

Maybe enable iwd support will trigger it, as iwd needs built-in kernel
support: https://git.kernel.org/pub/scm/network/wireless/iwd.git/

#iwd
