From b5a638fdccf5931af41815fa6e88779719ceb718 Mon Sep 17 00:00:00 2001 From: "Nícolas F. R. A. Prado" Date: Mon, 15 Apr 2024 17:49:32 -0400 Subject: drm/bridge: lt9611: 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 cd0a2c6a081ff67007323725b9ff07d9934b1ed8 ] 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.
