Subject: [PATCH 04/11] of: platform: use pdev as name for vars of type struct platform_device
Date:   Tue, 24 Apr 2018 19:30:44 +0200
Message-Id: <20180424173051.15099-5-brgl@bgdev.pl>
In-Reply-To: <20180424173051.15099-1-brgl@bgdev.pl>
References: <20180424173051.15099-1-brgl@bgdev.pl>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

It's a good convention to name struct device local variables 'dev'
and reserve 'pdev' for struct platform_device. Otherwise the code
sometimes becomes confusing to read. Rename all such instances in
of/platform.c
