Hello,everyone! When I make tpm emulator on Ubuntu 14.04， it return with some errors:

`[ 98%] Generating linux/tpmd_dev.ko
/home/ketty/TPM/tpm-emulator/build/tpmd_dev/linux/tpmd_dev.c: In function ‘tpmd_handle_command’:

I had follow https://github.com/PeterHuewe/tpm-emulator/issues/7#issuecomment-227621114, insert

`#if LINUX_VERSION_CODE < KERNEL_VERSION(3,19,0)
msg.msg_iov = &iov;
msg.msg_iovlen = 1;
#else
iov_iter_init(&msg.msg_iter, WRITE, &iov, 1, 1);
#endif`

But when I make it again, what I had inserted was missing, all back to the original.
