6.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Nícolas F. R. A. Prado <nfraprado@xxxxxxxxxxxxx> [ Upstream commit 275fafe58faa7fdb10fa245412696ecef676aac5 ] 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.
