From 455fd835e4f7c241727f41a142e29f44f46b290b Mon Sep 17 00:00:00 2001 From: Shaokun Zhang Date: Fri, 5 Jun 2020 17:43:41 +0800 Subject: [PATCH] drivers/perf: hisi: Fix wrong value for all counters enable [ Upstream commit 961abd78adcb4c72c343fcd9f9dc5e2ebbe9b448 ] In L3C uncore PMU drivers, bit16 is used to control all counters enable & disable. Wrong value is given in the driver and its default value is 1'b1, it can work because each PMU counter has its own control bits too. Let's fix the wrong value.
