Subject: [PATCH v5 15/36] PM / devfreq: tegra30: Add error messages to tegra_devfreq_target()
Date: Fri, 14 Aug 2020 03:06:00 +0300 [thread overview]
Message-ID: <20200814000621.8415-16-digetx@gmail.com> (raw)
In-Reply-To: <20200814000621.8415-1-digetx@gmail.com>
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.
