Subject: PROV: Move AES_GCM specialisation away from common cipher header
X-Git-Tag: openssl-3.0.0-alpha1~825
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=dc7aa029007da3849a04291a4c258587228daac8;p=oweals%2Fopenssl.git

PROV: Move AES_GCM specialisation away from common cipher header

The AES_GCM specialisation was defined in the common cipher header
providers/implementations/include/prov/ciphercommon_gcm.h, when it
should in fact be in a local providers/implementations/ciphers/
header.
