I'm not an expert of the device infrastructure of the Linux kernel, but I suspect it's because you don't return the number of bytes that you have taken into account. The store() method has the following prototype: ssize_t (*store)(struct class_device *, const char * buf, size_t count); So you must return the number of bytes that have been written.
