Subject: [PATCH RESEND 26/83] drm/meson: Switch to drm_mode_config_create_initial_state
Date: Thu, 05 Nov 2026 16:29:35 +0100	[thread overview]
Message-ID: <20261105-drm-no-more-config-reset-v1-26-1f58d1e33380@kernel.org> (raw)
In-Reply-To: <20261105-drm-no-more-config-reset-v1-0-1f58d1e33380@kernel.org>

drm_mode_config_reset() has a dual role: it creates the initial KMS
state at probe time, and resets hardware and software state during
suspend/resume cycles.

Since the two roles need different behaviors (notably for objects like
drm_private_obj that must persist across suspend/resume),
drm_mode_config_create_initial_state() was introduced to handle only
the initial state creation at probe time.

Switch to drm_mode_config_create_initial_state().
