From ff6cdc407f4179748f4673c39b0921503199a0ad Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 26 Nov 2024 14:47:22 +0100 Subject: x86/CPU/AMD: Terminate the erratum_1386_microcode array The erratum_1386_microcode array requires an empty entry at the end. Otherwise x86_match_cpu_with_stepping() will continue iterate the array after it ended. Add an empty entry to erratum_1386_microcode to its end.
