From a6c93afed38c242ccf4ec5bcb5ff26ff2521cf36 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Fri, 15 Apr 2011 11:14:38 +0100 Subject: [PATCH] ARM: perf: de-const struct arm_pmu This patch removes const qualifiers from instances of struct arm_pmu, and functions initialising them, in preparation for generalising arm_pmu usage to system (AKA uncore) PMUs. This will allow for dynamically modifiable structures (locks, struct pmu) to be added as members of struct arm_pmu.
