From 03d8e80beb7db78a13c192431205b9c83f7e0cd1 Mon Sep 17 00:00:00 2001 From: Mischa Jonker Date: Tue, 4 Jun 2013 11:45:48 +0200 Subject: [PATCH] perf: Add const qualifier to perf_pmu_register's 'name' arg This allows us to use pdev->name for registering a PMU device. IMO the name is not supposed to be changed anyway.
