As a result, `rzg2l_cru_format_from_pixel()` is guaranteed to return a non-NULL value, making the check redundant. Additionally, the return type of `rzg2l_cru_format_bytesperline()` is `u32`, but the code returned `-EINVAL`, a negative value. This mismatch is now resolved by removing the invalid error return path.
