From 402e473249cf62dd4c6b3b137aa845db0fe1453a Mon Sep 17 00:00:00 2001 From: Nicola Vetrini Date: Thu, 27 Jun 2024 13:48:08 +0200 Subject: [PATCH] x86/traps: 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.
