commit 1b9311da4b6364ed75561307bd8c3f50dd9046ce Author: Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx> AuthorDate: Tue May 21 15:59:50 2024 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Tue May 21 15:59:50 2024 +0200 x86/vpmu: 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.
