From 791ba97d1d1f5923303f159ac0da154e082a12f2 Mon Sep 17 00:00:00 2001 From: Philipp Deppenwiese Date: Mon, 30 Jul 2018 01:15:20 +0200 Subject: [PATCH] security/tpm: Use unique CBMEM names for TCPA logs Fix regression introduced in commit f18dc5c7 "Add TCPA logging functionality": Introduced TCPA log got overwritten in acpi.c of x86/arch, due to CBMEM name collision. Use a different cbmem name to have two independent TCPA logs.
