Subject: dm: i2c-gpio: Remove redundant dm_gpio_set_value() call
X-Git-Tag: KARO-TX6-2015-09-18~2193

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.
