From 2d91a839f5da3836e3b3f27452fe38a84fc403c6 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sun, 22 Oct 2023 01:10:41 -0700 Subject: crypto: rockchip - remove unnecessary alignmask for ahashes The crypto API's support for alignmasks for ahash algorithms is nearly useless, as its only effect is to cause the API to align the key and result buffers. The drivers that happen to be specifying an alignmask for ahash rarely actually need it. When they do, it's easily fixable, especially considering that these buffers cannot be used for DMA. In preparation for removing alignmask support from ahash, this patch makes the rockchip driver no longer use it. This driver didn't actually rely on it; it only writes to the result buffer in rk_hash_run(), already using put_unaligned_le32(). And this driver only supports unkeyed hash algorithms, so the key buffer need not be considered.
