[PATCH v2 13/19] PM / devfreq: rockchip-dfi: Pass private data struct to internal functions
From: Sascha Hauer <s.hauer@pengutronix.de>

Subsystem:
arm/rockchip soc support, device frequency (devfreq), device frequency event (devfreq-event), the rest · Maintainers:
Heiko Stuebner, MyungJoo Ham, Kyungmin Park, Chanwoo Choi, Linus Torvalds
The internal functions do not need the struct devfreq_event_dev *, so pass them the struct rockchip_dfi *. This is a preparation for adding perf support later which doesn't have a struct devfreq_event_dev *.
