[Intel-gfx] [PATCH] drm/i915: Avoid modeset when content protection changes

[Intel-gfx] [PATCH] drm/i915: Avoid modeset when content protection changes

[Sean Paul]

From: Sean Paul <seanpaul@chromium.org>

Instead of doing a full modeset to enable/disable content protection,
simply go through the update_pipe flow which was introduced in the
related patch below. This avoids flashing the screen every time the user
starts viewing protected content.
