[Buildroot] init module i2c-dev automatically

[Óscar Gómez Fuente]

OK,

For example a /etc/init.d/S18loadmod script like this:
---
#!/bin/sh
#
# load modules
#

MODULES_PATH="/etc/modules"

case "$1" in
start)
echo "Loading modules in ${MODULES_PATH}..."
for line in $(cat ${MODULES_PATH});
do
[[ $line = \#* ]] && continue
modprobe $line;
done
;;
stop)
;;
restart|reload)
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
esac

exit $?
