From c2a27584ff3b7f17da3ed2abfa3956f9d376e3da Mon Sep 17 00:00:00 2001 From: Dani Liberman Date: Mon, 11 Mar 2024 18:31:10 +0200 Subject: [PATCH] accel/habanalabs: separate nonce from max_size in cpucp_packet struct In struct cpucp_packet both nonce and data_max_size members are in an union overlapping each other. This is a problem as they both are used in attestation and info_signed packets. The solution here is to move the nonce member to a different union under the same structure.
