Subject: [PATCH v2 02/10] drm/panel/samsung-s6e63m0: Use refcounted allocation in place of devm_kzalloc()
Date: Fri, 08 May 2026 09:04:42 +0200	[thread overview]
Message-ID: <20260508-drm_panel_init_rm-v2-2-0bd4ac429971@redhat.com> (raw)
In-Reply-To: <20260508-drm_panel_init_rm-v2-0-0bd4ac429971@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.
