Those parts are between /* SENSORS ONLY START */ and /* SENSORS ONLY END */ markers. -This function should only return an error (any value != 0) if there is -some reason why no more detection should be done anymore. If the -detection just fails for this address, return 0. +Returning an error different from -ENODEV in a detect function will cause +the detection to stop: other addresses and adapters won't be scanned. +This should only be done on fatal or internal errors, such as a memory +shortage or i2c_attach_client failing.
