In Linux v6.12, commit 88a2f6468d01 ("struct fd: representation change")
removed the 'struct file' pointer from 'struct fd'. This breaks building
the NVSCIIPC driver that tries to directly access the 'file' pointer
from the 'fd' structure. Fix this by using the helper macros 'fd_empty'
and 'fd_file' as necessary to fix the build.

Build NvSciIpc KMD for DRIVE x86
================================
1) install kernel header package
sudo apt-get install linux-headers-`uname -r`
check version of desktop using "uname -r" command.
kernel version must be 5.4.0+.
2) link common header files (NVIDIA internal dev only)
export NVSCIIPC_INCLUDE=${PWD}/../../../include
ln -s ${NVSCIIPC_INCLUDE}/linux ./
ln -s ${NVSCIIPC_INCLUDE}/uapi ./
3) build
make -C /lib/modules/`uname -r`/build M=${PWD} modules
4) install NvSciIpc KMD
sudo make -C /lib/modules/`uname -r`/build M=${PWD} modules_install
sudo depmod -a
nvsciipc.ko will be installed in /lib/modules/`uname -r`/updates/nvsciipc.ko
[NOTE] If kernel module installation is failed by missing signing key, follow steps below
** create x509.genkey
echo -e "[ req ] \n\
default_bits = 4096 \n\
distinguished_name = req_distinguished_name \n\
prompt = no \n\
x509_extensions = myexts \n\
\n\
[ req_distinguished_name ] \n\
CN = Modules \n\
\n\
[ myexts ] \n\
basicConstraints=critical,CA:FALSE \n\
keyUsage=digitalSignature \n\
subjectKeyIdentifier=hash \n\
authorityKeyIdentifier=keyid" > x509.genkey
** generate signing key
openssl req -new -nodes -utf8 -sha512 -days 36500 -batch -x509 -config x509.genkey -outform DER -out signing_key.x509 -keyout signing_key.pem
** move signing key to kernel module folder of desktop
sudo mv signing_key.* /lib/modules/`uname -r`/build/certs/
5) clean
make -C /lib/modules/`uname -r`/build M=${PWD} clean
6) load NvSciIpc KMD
You can load NvSciIpc KMD during desktop boot.
sudo vi /etc/modules-load.d/modules.conf
add "nvsciipc" to this file
For manual loading KMD, do "sudo insmod nvsciipc.ko"
