From 33eb09a02e8d8fad976019694196eec2cc210d62 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 25 Jul 2019 22:21:36 +0200 Subject: i2c: designware: make use of devm_gpiod_get_optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a semantical change: if devm_gpiod_get_optional returns -ENOSYS this is passed as error to the caller. This effectively reverts commit d1fa74520dcd ("i2c: designware: Consider SCL GPIO optional") which shouldn't be necessary any more since gpiod_get_optional doesn't return -ENOSYS any more with GPIOLIB=n.
