From 12b731dd46d9ee646318e6e9dc587314a3908a46 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 16 Jun 2018 21:56:36 +0900 Subject: [PATCH] i2c: gpio: initialize SCL to HIGH again It seems that during the conversion from gpio* to gpiod*, the initial state of SCL was wrongly switched to LOW. Fix it to be HIGH again.
