From 795c4e367b7bfa268a732b99de7cd3f79469cf3f Mon Sep 17 00:00:00 2001 From: Nicola Vetrini Date: Wed, 3 Apr 2024 09:37:00 +0200 Subject: [PATCH] x86/amd: address violations of MISRA C Rule 20.7 MISRA C Rule 20.7 states: "Expressions resulting from the expansion of macro parameters shall be enclosed in parentheses". Therefore, some macro definitions should gain additional parentheses to ensure that all current and future users will be safe with respect to expansions that can possibly alter the semantics of the passed-in macro parameter. No functional change.
