This should really be written like so:
if (copy_to_user((void __user *)ioctl_param, &temp,
sizeof(temp)))
return -EFAULT;
temp is really the wrong name. "temp" is for temperatures. "tmp" means
temporary. But also "tmp" is wrong here because it's not a temporary
variable. It's better to call it "regs" here.
