Subject: Use proper memory type in TZ backend's addGcmAAD()
X-Git-Tag: accepted/tizen/7.0/unified/20230717.162659~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b43f739a1f13d98004ffa73f5f151f772ca9dce2;p=platform%2Fcore%2Fsecurity%2Fkey-manager.git

Use proper memory type in TZ backend's addGcmAAD()

We need TEEC_VALUE_INOUT to properly read the return code from
op.params[0].value.a.
