Subject: [PATCH 21/36] drm/tegra: dc: Do not needlessly deassert reset
Date: Tue, 20 Jan 2015 11:48:40 +0100 [thread overview]
Message-ID: <1421750935-4023-22-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1421750935-4023-1-git-send-email-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Commit 9c0127004ff4 ("drm/tegra: dc: Add powergate support") changed the
driver's ->probe() implementation to deassert the module reset, and with
there being nobody else to assert it until ->remove() there is no need
to deassert again later on.
