Subject: [PATCH 0/2][RFC v2] Change trace point to cover all runtime usage count

Currently some code flow of runtime usage count changes is not covered by 
the rpm_runtime_usage tracepoints. Adjust corresponding tracepoints to monitor
all the runtime usage count changes.

Chen Yu (2):
  PM-runtime: Move all runtime usage related function to runtime.c
  PM-runtime: change the tracepoints to cover all usage_count
