evdi-dkms FTBS with linux 6.5 on jammy

[Andrea Righi]

[Impact]

/var/lib/dkms/evdi/1.12.0+dfsg/build/evdi_encoder.c:26:9: error: implicit declaration of function ‘drm_encoder_cleanup’; did you mean ‘drm_crtc_cleanup’? [-Werror=implicit-function-declaration]
   26 | drm_encoder_cleanup(encoder);
      | ^~~~~~~~~~~~~~~~~~~
      | drm_crtc_cleanup

[Test case]

 $ sudo apt install evdi-dkms

[Fix]

Backport the required changes to properly support the new 6.5 kernel ABI.

[Regression potential]

We may experience regressions in systems that are using the EVDI driver (multiple screens), especially with the new 6.5 kernel.

Hello Andrea, or anyone else affected,

Accepted evdi into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/evdi/1.12.0+dfsg-0ubuntu2~22.04.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I installed version 1.12.0+dfsg-0ubuntu2~22.04.3. Now the kernel module builds and works as expected with a DisplayLink device.
