Subject: [PATCH v2 13/18] iio: imu: inv_mpu6050: Simplify with dev_err_probe()

 CAUTION: This email originated from outside of the organization. Please make sure the sender is who they say they are and do not click links or open attachments unless you recognize the sender and know the content is safe.

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and also it prints the error value.
