Subject: [PATCH 5/6] gpio: htc-egpio: use devm_platform_ioremap_resource()
Date: Wed, 2 Oct 2019 19:02:48 +0200 [thread overview]
Message-ID: <20191002170249.17366-6-brgl@bgdev.pl> (raw)
In-Reply-To: <20191002170249.17366-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
There's no need to use the nocache variant of ioremap(). Switch to
using devm_platform_ioremap_resource().
