From 30cb32c7ec5ea7a0696d4b2edfb4a69fae56263b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?N=C3=ADcolas=20F=2E=20R=2E=20A=2E=20Prado?= Date: Mon, 15 Apr 2024 17:49:33 -0400 Subject: [PATCH] drm/bridge: lt9611uxc: Don't log an error when DSI host can't be found MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 6d9e877cde7e9b516a9a99751b8222c87557436d ] Given that failing to find a DSI host causes the driver to defer probe, make use of dev_err_probe() to log the reason. This makes the defer probe reason available and avoids alerting userspace about something that is not necessarily an error.
