I did not receive answer for my previous question here - why you need
two samsung_pin_ctrl* variables? Why you need additional match_data?
Just make it:
ctrl = of_device_get_match_data(&pdev->dev);
ctrl += id;
To me it looks simpler and obvious. Having two variables for the same
brings questions.
If you do not agree, say it. I don't mind. But I would appreciate if
comments were not ignored.
Best regards,
Krzysztof
