From 76382aa2ce811d4bb53f8c617590fb36681ce169 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 26 Apr 2015 11:05:38 +0800 Subject: [PATCH] dm: i2c-gpio: Remove redundant dm_gpio_set_value() call dm_gpio_set_dir_flags() will also set gpio output value when switching to gpio output. So it's not necessary to call dm_gpio_set_value() after dm_gpio_set_dir_flags() call.
