From 2d23ed04de933625bc777cc474d2cd9a2a3fa860 Mon Sep 17 00:00:00 2001 From: "Suzuki K. Poulose" Date: Fri, 12 Jun 2015 15:39:28 +0100 Subject: [PATCH] arm64: perf: Remove unnecessary printk ARM64 pmu prints an error message in event_init() when no hardware PMU is available. This is pretty annoying as it keeps printing the message for every single trial, flooding the kernel logs, unnecessarily. The return code is sufficient for the user to figure out the reason.
