Use the dev_err_probe function instead of dev_err in the probe function
so that the printed messge includes the return value and also handles
-EPROBE_DEFER nicely.

Please avoid a typo in such a wording.


How do you think about to avoid empty descriptions according to addresses
in applied recipient lists?
