[V2,08/10] video: pxafb: Remove cpufreq policy notifier

Message ID 56ea0fb68b99d343b093bc517024356a18f780e7.1563862014.git.viresh.kumar@linaro.org (mailing list archive)

Commit Message

Viresh Kumar July 23, 2019, 6:14 a.m. UTC
The cpufreq policy notifier's CPUFREQ_ADJUST notification is going to
get removed soon.

The notifier callback pxafb_freq_policy() isn't doing anything apart
from printing a debug message on CPUFREQ_ADJUST notification. There is
no point in keeping an otherwise empty callback and registering the
notifier.

Remove it.
