Subject: [PATCH 0/3] drm/bridge: ite-it66121: use bulk read, improve probe logging
Date: Thu, 15 Oct 2026 11:48:45 +0200 [thread overview]
Message-ID: <20261015-drm-ite-it66121-log-probe-errors-v1-0-7fd6994e0be0@bootlin.com> (raw)
This small series improves it66121_probe() in various ways:
* use a bulk read for reading the vendor and device ID registers
* log errors in ID reading and matching instead of failing silently
* on successful probe be quiet on !DEBUG, more informative on DEBUG
