From c4b496c9f7724f205570107aaf678876428f8f79 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 30 Nov 2020 15:27:57 +0100 Subject: [PATCH] iio: adc: xilinx: use helper variable for &pdev->dev [ Upstream commit 9d8fd2a06a2bcce8eada1bad26cbe0fbfc27cdf4 ] It's more elegant to use a helper local variable to store the address of the underlying struct device than to dereference pdev everywhere.
