From 771c4e39632d6d8a36668242bcc71f93cfc2842e Mon Sep 17 00:00:00 2001 From: Nicola Vetrini Date: Mon, 4 Mar 2024 10:46:25 +0100 Subject: [PATCH] xen/arm: smmuv3: 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.
