Subject: [PATCH 0/3] device: core: Adjust device probe log messages to ease
 error detection

This series adjusts log message's log levels and helper functions to
make it easier to detect issues with the probe of devices.

This is the rationale:

- The dev_* printk variants should be used to log information related to
  the probe of a device so that the messages get the device's metadata
  attached and can easily be correlated to it.
- Issues in the probe of a device should be logged at the error level.
  If it is likely that an issue has ocurred, but not guaranteed, log at
  the warning level.

      driver: core: Log probe failure as error and with device metadata
      driver: core: Use dev_* instead of pr_* so device metadata is added
      device: core: Log warning for devices pending deferred probe on timeout
