I am not sure why this change is needed. Also it seems that the driver
leaks DT-created pdata on unload.

Pdata is now a member of gpio_keys_polled_dev now and that one is
kzalloc'ed at probe and kfree'd at the removal and errors. I see no
leaks there.

I could kzalloc and kfree gpio_keys_polled_dev independently instead,
to avoid all those pointer changes if you think it's better.

This is mostly a clone from the dt handling in gpio_keys, and
comparing both now,
I see that it will leak on pdata->buttons, so I will fix that.

Please use of_match_ptr() instead.

Thanks for the suggestion, I will implement that.
