Merge branch 'fixes' of https://git.kernel.org/pub/scm/linux/kernel/git/mzx/devfreq into pm-devfreq
Pull devfreq fixes for v4.7 from MyungJoo Ham. * 'fixes' of https://git.kernel.org/pub/scm/linux/kernel/git/mzx/devfreq: PM / devfreq: fix initialization of current frequency in last status PM / devfreq: exynos-nocp: Remove incorrect IS_ERR() check PM / devfreq: remove double put_device PM / devfreq: fix double call put_device PM / devfreq: fix duplicated kfree on devfreq pointer PM / devfreq: devm_kzalloc to have dev pointer more precisely
