From 99481a098837d6adc24a82d0d3123e675b3e191b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Wed, 29 May 2024 14:06:24 +0200 Subject: [PATCH] accel: Restrict probe_access*() functions to TCG MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This API is specific to TCG (already handled by hardware accelerators), so restrict it with #ifdef'ry. Remove unnecessary stubs.
