In my opinion it is better to use dev_err_probe() as done here because:

1. If it's -EPROBE_DEFER it will be under debug level already
2. If it's anything else, its an error and the logs are useful

I've ran into both ends of this now (failure of a platform dependency to
load, be it a bug in the driver, or just failing to select said driver),
and I've seen issues where new integrators (say you're bringing up a new
board) leave something out, etc, and run into issues because of that.

Thanks,
Andrew
