When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
And using dev_err_probe() can reduce code size, the error value
gets printed.

drm/panel: Delete panel on mipi_dsi_attach() failure 2021-10-14T19:55:12+00:00 Brian Norris briannorris@chromium.org 2021-09-24T00:33:55+00:00 9bf7123bb07f98dc76acb5daa91248e6f95713cb Many DSI panel drivers fail to clean up their panel references on mipi_dsi_attach() failure, so we're leaving a dangling drm_panel reference to freed memory. Clean that up on failure. Noticed by inspection, after seeing similar problems on other drivers. Therefore, I'm not marking Fixes/stable.
