[PATCH 06/10] drm/panel/tdo-tl070wsh30: Use refcounted allocation in place of devm_kzalloc()
From: Albert Esteve
Date: Thu May 07 2026 - 07:54:18 EST
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.
