Subject: [PATCH v7 7/8] drm: writeback: Modify prepare_writeback_job helper
Date: Tue, 10 Nov 2026 11:46:36 +0530 [thread overview]
Message-ID: <20261110061637.2500929-8-suraj.kandpal@intel.com> (raw)
In-Reply-To: <20261110061637.2500929-1-suraj.kandpal@intel.com>
The prepare_writeback_job() connector helper hook needs access to
the parent drm_connector object as well as the drm_writeback_connector
object itself. So, pass in the top level drm_connector and traverse
down to drm_writeback_connector rather than passing in the lower
level object and traversing back up. This also makes it uniform
with the params passed to other drm_connector_helper_funcs hooks.
