Subject: [PATCH v2 2/4] media: staging: tegra-vde: Runtime PM is always available on Tegra
Date: Wed, 24 Jun 2020 18:08:45 +0300 [thread overview]
Message-ID: <20200624150847.22672-3-digetx@gmail.com> (raw)
In-Reply-To: <20200624150847.22672-1-digetx@gmail.com>
Runtime PM is always available on Tegra nowadays since commit 40b2bb1b132a
("ARM: tegra: enforce PM requirement"), hence the case of unavailable RPM
doesn't need to be handled.
