6.6-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.
