From 4a75f2ffc034544e383652e1485e13709e389f85 Mon Sep 17 00:00:00 2001 From: Nicola Vetrini Date: Thu, 25 Apr 2024 09:51:31 +0200 Subject: [PATCH] x86/mm: 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.
