Subject: [PATCH 6/9] gpio: ath79: use devm_platform_ioremap_resource_nocache()
From: Bartosz Golaszewski <bgolaszewski@...libre.com>
Use the new devm_platform_ioremap_resource_nocache() helper for memory
range mapping instead of devm_ioremap_nocache() combined with a call to
platform_get_resource().
