[PATCH v3 15/39] PM / devfreq: tegra30: Add error messages to tegra_devfreq_target()

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

 



It's useful to now when something goes wrong instead of failing silently,
so let's add error messages to tegra_devfreq_target() to prevent situation
where it fails silently.
