[PATCH 1/6] PM / devfreq: event: Remove the error log of devfreq_event_get_edev_by_phandle()

[Chanwoo Choi]

This patch just removes the error log when devfreq_event_get_edev_by_phandle()
fail to get the instance of devfreq-event device. It is related to sequence of
the probe() of each driver. So, this error log might show the always during
kernel booting. Instead, each driver using this function can show the
appropriate error log.
