Hi Dimitry,
Thanks for the patch

There is no reason to pass platform device to debugfs just to get the
tsens_priv from it. Not to mention that for TSENS_V0 the platform device
(gcc) might have other device data. Pass the tsens_priv data to debugfs
callbacks directly.

You anyways have to pass pdev here, as it is used for referencing dev
name below. So drop sending tsens_priv as well. You can get it via
platform_get_drvdata as in the original code. I am okay with the change
in using priv instead of pdev as private pointer in the fops.
