From 272377aa0e3dddeec3f568c8bb9d12c7a79d8ef5 Mon Sep 17 00:00:00 2001 From: "Nícolas F. R. A. Prado" Date: Mon, 15 Apr 2024 17:49:34 -0400 Subject: drm/bridge: tc358775: 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 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.
