When a uclass definition is missing for an enabled driver, the board cannot boot, and without any extra debug option enabled the following error is displayed: initcall_run_r(): initcall initr_dm() failed ### ERROR ### Please RESET the board ### There is a debug message using dm_warn(), which is not displayed by default. Since this is a fatal error preventing the board from booting, the log level should be at least ERROR.
