Subject: [PATCH v5 04/11] drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state
Date: Tue, 11 Jun 2019 12:08:18 -0400	[thread overview]
Message-ID: <20190611160844.257498-5-sean@poorly.run> (raw)
In-Reply-To: <20190611160844.257498-1-sean@poorly.run>

From: Sean Paul <seanpaul@chromium.org>

Everyone who implements connector_helper_funcs->atomic_check reaches
into the connector state to get the atomic state. Instead of continuing
this pattern, change the callback signature to just give atomic state
and let the driver determine what it does and does not need from it.

Eventually all atomic functions should do this, but that's just too much
busy work for me.

Changes in v3:
- Added to the set
Changes in v4:
- None
Changes in v5:
- intel_digital_connector_atomic_check declaration moved to i915_atomic.h
