** Description changed:

+ [SRU Justification]
+ 
+ [Impact]
+ 
+ Failed to compile intel-ipu6-dkms against v6.12 kernels.
+ 
+ [Fix]
+ 
+ A few Ubuntu sauced changes. Also being upstreamed in:
+ * https://github.com/intel/ipu6-drivers/pull/283
+ 
+ [Test Case]
+ 
+ So far there is no official v6.12 kernel available, but one may install 
experimental linux-unstable/plucky kernels from 
https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/experimental-unstable.
 With that install intel-ipu6-dkms from -proposed pocket, and issue:
+ ```
+ $ sudo dkms install ipu6-drivers/0~git202407190257.9369b88e-0ubuntu2 -k 
$(uname -r)
+ $ sudo dkms status
+ ```
+ The installation should complete successfully.
+ 
+ [Where problems could occur]
+ 
+ While this is an initial port to v6.12, there might be changes that
+ doesn't reflect in the API changes.
+ 
+ [Other Info]
+ 
+ Only necessary for when with the potential chance to be compiled against
+ v6.12 kernels. Nominate for plucky and oracular for
+ ipu6-drivers/oracular may compile against linux-hwe-6.XX/noble then.
