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")
