Hello.

According to kernel's documentation for sysfs:

- store() should return the number of bytes used from the buffer. If the
  entire buffer has been used, just return the count argument.

So, it should return (ssize_t) 2 for echo "2" > /sys/devices/platform/faustus/fan_mode (actually, echo append a '\n' to its argument, and really write '2\n' to the sysfs file, which is 2 bytes).
But please don't hardcode this (ssize_t) 2 - user may write '255\n' to the sysfs file or so.
