I want to use gpio19 as general purpose output. This port is used from I2C in v2.7. One solution is to remove /etc/modules.d/50-i2c-gpio-custom und reboot. For some special reason I wish to use the port without removing that file and rebooting.

rmmod i2c_gpio_custom does not work:

root@carambola2:# cat /sys/kernel/debug/gpio
GPIOs 0-29, ath79:
gpio-0 (carambola2:green:wla) out lo
gpio-13 (carambola2:orange:et) out lo
gpio-14 (carambola2:orange:et) out lo
gpio-18 (sda ) in lo
gpio-19 (scl ) in lo
