[PATH v3 1/3] iio: adc: xilinx: use helper variable for &pdev->dev

From: Bartosz Golaszewski
Date: Mon Nov 30 2020 - 09:29:06 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

It's more elegant to use a helper local variable to store the address
of the underlying struct device than to dereference pdev everywhere.
