Right, the patch as it stands doesn't change anything. However, it is also broken as it stands. As I said before, CRYPTO_MINALIGN is not something that is guaranteed by the Crypto API, it is simply a statement of whatever kmalloc returns. So if kmalloc is no longer returning CRYPTO_MINALIGN-aligned memory, then those drivers that need this alignment for DMA will break anyway. If you want the Crypto API to guarantee alignment over and above that returned by kmalloc, the correct way is to use cra_alignmask.
