[PATCH 4.8 008/140] PM / devfreq: event: remove duplicate devfreq_event_get_drvdata()

[Greg Kroah-Hartman]

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lin Huang <hl@xxxxxxxxxxxxxx>

commit c8a9a6daccad495c48d5435d3487956ce01bc6a1 upstream.

there define two devfreq_event_get_drvdata() function in devfreq-event.h
when disable CONFIG_PM_DEVFREQ_EVENT, it will lead to build fail. So
remove devfreq_event_get_drvdata() function.

Fixes: f262f28c1470 ("PM / devfreq: event: Add devfreq_event class")
