Bug Description

[Impact]

nvidia-dkms-470-server fails to build with linux 6.2:

/var/lib/dkms/nvidia-srv/470.161.03/build/nvidia/nv-acpi.c:84:19: error: initialization of ‘void (*)(struct acpi_device *)’ from incompatible pointer type ‘int (*)(struct acpi_device *, int)’ [-Werror=incompatible-pointer-types]
84 | .remove = nv_acpi_remove_two_args,
| ^~~~~~~~~~~~~~~~~~~~~~~

[Fix]

Change the driver to support also the 6.2 kernel ABI.

[Test case]

With linux 6.2 installed, run:

$ sudo apt install nvidia-dkms-470-server

[Regression potential]

We may experience regressions in newer kernels (>= 6.2) that are using nvidia-dkms-470-server (source code for previous kernels remain unchanged).
