Subject: [PATCH v4 10/16] PM / devfreq: tegra: Mark ACTMON's governor as immutable
Date: Thu, 2 May 2019 02:38:09 +0300 [thread overview]
Message-ID: <20190501233815.32643-11-digetx@gmail.com> (raw)
In-Reply-To: <20190501233815.32643-1-digetx@gmail.com>
The ACTMON's governor supports only the Tegra's devfreq device and there
is no need to use any other governor, hence let's mark Tegra governor as
immutable to permanently stick it with Tegra's devfreq device.
