From 7e5fbd1e0700f1bdb94508f84ec2aeb01eed7b12 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 11 Jan 2017 12:59:50 -0800 Subject: [PATCH] net: mdio-gpio: Convert to use gpiod functions where possible Using gpiod functions lets us use functionality which is not available with gpio functions. There is no gpiod function to match devm_gpio_request_one, so leave it in place and use gpio_to_desc() to convert absolute pin numbers to gpio descriptors.
