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.

I don't think this is needed:

Hmm, that's a bit borderline, I'd say. The change to

What's borderline exactly? devm_request_threaded_irq_probe() is coming,
right? If it is accepted this hunk is useless and soon should be
replaced with proper one.

Instead of making many trivial changes doing the same, all these series
should be aligned.

devm_request_irq/devm_request_threaded_irq_probe seems like
something for another series. But for now, I think I'll accept
this as it is since it fits within the scope of this current
series.

Best regards,
Krzysztof
