Merge tag 'devfreq-next-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for v5.16 from Chanwoo Choi:

"1. Minor update for exynos-ppmu devfreq-event driver

  - Devicetree naming convention requires the device node names
    to use hyphens instead of underlines. In order to support
    this requirement, changes the code with hyphens.

  - Simplify parsing event-type from devicetree without behavior
    changes.

 2. Strengthen check for freq_table in devfreq core

  - Check whether both freq_table is not NULL and size of freq_table
    is not zero in order to prevent the error by mistake of devfreq
    driver developer.
