Thanks, like the previous patch this looks much better now!
A couple minor nits I noticed while reading this latest version:

It would be helpful if the comment mentioned the -1 case:
* @crypto_key_slot: the key slot to use for inline crypto (-1 if none)

Since CONFIG_SCSI_UFS_CRYPTO is a bool this should use #ifdef, not IS_ENABLED().
