[PATCH] cpufreq: exynos: fix hang in pm handler due to frequency mismatch

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jonghwan Choi <jhbird.choi@xxxxxxxxxxx>

When pm handler set freq & voltage, frequency mismatch occurred.
Because freqs.new isn't set in pm handler.
