Subject: [PATCH 01/36] crypto: powerpc/aes - Rename struct aes_key

From: Eric Biggers <[email-masked]>
Date: Sun, 4 Jan 2026 21:12:34 -0800

Rename struct aes_key in aesp8-ppc.h and aes-gcm-p10-glue.c to
p8_aes_key and p10_aes_key, respectively.  This frees up the name to use
in the library API in <crypto/aes.h>.
