From: Ulf Hansson <ulf.hans...@linaro.org> To be able to deactivate resourses in suspend, the resourses must first be surely active. This is done with a pm_runtime_get_sync. Once the resourses are restored to active state again in resume, the runtime pm usage count can be decreased with a pm_runtime_put.
