For some it's OK to fail and for others where it's not a dev_err() is reported, for example in max9271_verify_id(). Will this not log error messages in situations where there really is no error? Maybe dev_info() is a better choice if you want to increase verbosity? > "%s: register 0x%02x read failed (%d)\n", > __func__, reg, ret); > > -- > 2.33.1 > -- Regards, Niklas Söderlund
