Date: Tue, 20 Jan 2015 11:48:40 +0100 From: Thierry Reding <thierry.reding@...il.com> To: dri-devel@...ts.freedesktop.org Cc: linux-tegra@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 21/36] drm/tegra: dc: Do not needlessly deassert reset From: Thierry Reding <treding@...dia.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.
