Subject: [PATCH 0/3] media: v4l: async: add helper API v4l2_async_pad_init_and_register_subdev()
Date: Tue, 10 Feb 2026 16:42:20 -0500 [thread overview]
Message-ID: <20260210-v4l2_init_register-v1-0-8fe43f7d349f@nxp.com> (raw)
Add the helper API v4l2_async_pad_init_and_register_subdev(), which
combines media_entity_pads_init(), v4l2_subdev_init_finalize(), and
v4l2_async_register_subdev() into a single call.
Reduce code duplication and simplify error handling in drivers.
Only change dwc and cdns. If agree add API, more driver can be simplified.
