I prefer seeing pdev->dev.parent - as it is more obvious (to me) what the 'pdev' is than what 'parent' would be. I'd use the local variable only when it shortens at least one of the lines so that we avoid splitting it. After that being said - I'm not going to argue over this change either if one who is improving the driver wants to use the "helper" variable here. Best Regards -- Matti

And I believe the quoted one is exactly the case of what you are saying above.

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node() so that gpiolib can be cleaned a bit, so let's switch to the generic fwnode property API. While at it switch the rest of the calls to read properties in bd957x_probe() to the generic device property API as well. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
