Ah. It's that that third one that really introduced the dependency so possibly
only that one should be listed with a fixes tag. However the right fix
at that point was to select CRYPTO_DES which then changed to CRYPTO_LIB_DES
only after the second patch.
It's not a fix for the first patch so that should probably not be there.
Otherwise, looks correct to me.

Thanks, that's right, I will send v2 and keep two fixes,
Fixes: 04007b0e6cbb ("crypto: des - split off DES library from generic DES cipher driver")
Fixes: 894b68d8be4b ("crypto: hisilicon/des - switch to new verification routines")
then remove fix tag because it only introduces one driver:
Fixes: 915e4e8413da ("crypto: hisilicon - SEC security accelerator driver")

When CRYPTO_DEV_HISI_SEC=y, below compilation error is found after
'commit 894b68d8be4b ("crypto: hisilicon/des - switch to new verification routines")':
drivers/crypto/hisilicon/sec/sec_algs.o: In function `sec_alg_skcipher_setkey_des_cbc':

This because DES library has been moved to lib/crypto in this commit
'04007b0e6cbb ("crypto: des - split off DES library from generic DES cipher driver")'.
Fix this by selecting CRYPTO_LIB_DES in CRYPTO_DEV_HISI_SEC.
Fixes: 04007b0e6cbb ("crypto: des - split off DES library from generic DES cipher driver")
