Public bug reported:
When upgrading to kernel 6.11.0-17-generic, the vhba DKMS module fails
to build with the following error:
/var/lib/dkms/vhba/20240202/build/vhba.c:1087:15: error: initialization of
‘void (*)(struct platform_device *)’ from incompatible pointer type ‘int
(*)(struct platform_device *)’ [-Werror=incompatible-pointer-types]
1087 | .remove = vhba_remove,
| ^~~~~~~~~~~
/var/lib/dkms/vhba/20240202/build/vhba.c:1087:15: note: (near initialization
for ‘vhba_platform_driver.<anonymous>.remove’)
cc1: all warnings being treated as errors
This appears to be due to a mismatch between the expected function
signature for the .remove callback in the platform_driver structure and
the implementation in the vhba module.
Steps to reproduce:
1. Upgrade to kernel 6.11.0-17-generic.
2. Attempt to build the vhba DKMS module.
3. Observe the build failure.
Additional information:

- Kernel version: 6.11.0-17-generic
- vhba module version: 20240202
