Subject: [PATCH v3 17/20] drm/drv: Switch skeleton to drm_mode_config_create_initial_state()
Date: Fri, 24 Apr 2026 12:18:57 +0200 [thread overview]
Message-ID: <20260424-drm-mode-config-init-v3-17-8b68d9db0d8b@kernel.org> (raw)
In-Reply-To: <20260424-drm-mode-config-init-v3-0-8b68d9db0d8b@kernel.org>
The driver skeleton currently recommends calling
drm_mode_config_reset() at probe time to create the initial state.
Now that drm_mode_config_create_initial_state() exists to handle
initial state allocation without hardware side effects, update the
skeleton to recommend it instead.
