Subject: [PATCH 2/6] drm/panel/truly-nt35597: Use refcounted allocation in place of devm_kzalloc()
Date: Tue, 08 Jul 2025 15:35:14 -0500	[thread overview]
Message-ID: <20250708-b4-simple-panel-api-convert-july-v1-2-630902123ea1@redhat.com> (raw)
In-Reply-To: <20250708-b4-simple-panel-api-convert-july-v1-0-630902123ea1@redhat.com>

Move to using the new API devm_drm_panel_alloc() to allocate the
panel. In the call to the new API, avoid using explicit type and use
__typeof() for more type safety.
