Subject: [PATCH v2 08/12] drm/i915/display: Make icl_dsi_frame_update use _fw too
Date: Fri, 12 Dec 2025 15:35:12 +0100 [thread overview]
Message-ID: <20251212143504.973839-22-dev@lankhorst.se> (raw)
In-Reply-To: <20251212143504.973839-14-dev@lankhorst.se>
Don't use the dmc lock inside the vblank critical section,
not even as last call.
