avc: denied { open } for pid=7530 comm="android.hardwar" path="/sys/devices/virtual/timed_output/vibrator/enable" dev="sysfs" ino=20519 scontext=u:r:android_hardware_vibrator_1_0_service:s0 tcontext=u:object_r:sysfs:s0 tclass=file permissive=1
avc: denied { call } for pid=9173 comm="Binder:7735_C" scontext=u:r:system_server:s0 tcontext=u:r:android_hardware_vibrator_1_0_service:s0 tclass=binder permissive=1
