Subject: [PATCH 1/5] iio: adc: xilinx: use helper variable for &pdev->dev
Date: Mon, 26 Oct 2020 14:36:05 +0100 [thread overview]
Message-ID: <20201026133609.24262-2-brgl@bgdev.pl> (raw)
In-Reply-To: <20201026133609.24262-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
It's more elegant to use a helper local variable to store the address
of the underlying struct device than to dereference pdev everywhere.
