From 6bccbb1794eae796e211d2e9e3a7de4aae86de68 Mon Sep 17 00:00:00 2001 From: Nicola Vetrini Date: Mon, 14 Aug 2023 09:58:37 +0200 Subject: [PATCH] x86/hpet: make variable 'per_cpu__cpu_bc_channel' static The variable is only ever used inside the file where it's defined, therefore it can have static storage. This also resolves a violation of MISRA C:2012 Rule 8.4 due to the absence of a declaration prior to the definition.
