"public header" is ambiguous here. blk-crypto.h is the "public header" for
upper layers, but blk-crypto-profile.h is the "public header" for drivers.
Maybe write "blk-crypto-profile.h, which is included by drivers".

It should go in the '#ifdef CONFIG_BLK_INLINE_ENCRYPTION' section.

Otherwise I guess this patch is fine. The exact same argument would also apply
to blk_crypto_get_keyslot(), blk_crypto_put_keyslot(), and
__blk_crypto_evict_key(), though. It might be worth handling them all in one
patch.
