Subject: [PATCH] drm/panel: ltk050h3146w: use dev_err_probe wherever possible
This is only a cosmetic change.
This replaces a hand-crafted EPROBE_DEFER handling for deciding to print
an error message with dev_err_probe.
A side-effect is that dev_err_probe also adds a debug message when it's
not EPROBE_DEFER, but this is seen as an improvement.
