Subject: crypto: api - Add CRYPTO_MINALIGN_ATTR to struct crypto_alg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=edf18b9108f5025f9e83b2c167c9122954acbc62;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: api - Add CRYPTO_MINALIGN_ATTR to struct crypto_alg

The struct crypto_alg is embedded into various type-specific structs
such as aead_alg.  This is then used as part of instances such as
struct aead_instance.  It is also embedded into the generic struct
crypto_instance.  In order to ensure that struct aead_instance can
be converted to struct crypto_instance when necessary, we need to
ensure that crypto_alg is aligned properly.

This patch adds an alignment attribute to struct crypto_alg to
ensure this.
