Hi Srdjan and everyone.
Thanks for pointing that out, I have updated my function.
ssize_t memo_write(struct file *filp, const char __user *buf, size_t count,
loff_t *offp){
printk("write function\n");
ssize_t temp = -ENOMEM;
return temp;
}
However with a clean build reboot and insmod, I am having the same error.
I'm sure I must be missing something obvious. What could be causing this?
