Subject: [PATCH v5 6/7] backlight: gpio: use a helper variable for &pdev->dev
Date: Mon, 7 Oct 2019 05:31:59 +0200 [thread overview]
Message-ID: <20191007033200.13443-7-brgl@bgdev.pl> (raw)
In-Reply-To: <20191007033200.13443-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Instead of dereferencing pdev each time, use a helper variable for
the associated device pointer.
