s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined in the platform data of the i2c device. When DT is not enabled, the above function always returns -EINVAL. Since there can be some i2c devices which don't need to configure any gpio lines, the probe of such devices would fail here. Changing the default return value to success would fix this issue.
