Title:
  Failed to build against linux-6.11

Status in ipu6-drivers package in Ubuntu:
  Fix Released
Status in ipu6-drivers source package in Noble:
  In Progress
Status in ipu6-drivers source package in Oracular:
  Fix Released

Bug description:
  [SRU Justification]

  [Impact]

  Upstream commit d69d804845985 ("driver core: have match() callback in
  struct bus_type take a const *") added const attribute the the second
  parameter of the match callback, and this fails the build against
  linux-6.11.

  [Fix]

  Ubuntu sauced change to accommodate to the API change. Also proposed
  to the upstream as https://github.com/intel/ipu6-drivers/pull/261.

  [Test Case]

  Install the built dkms binary package and linux-headers-
  oem-24.04b/noble. The dkms build should be triggered and complete
  successfully.

  [Where problems could occur]

  For Oracular, there is a new upstream release mostly for a next Intel
  platform, but there are also code refinements as well. No specious
  side effect found.

  For Noble, there is only preprocessor macros to satisfy the API
  compatibility.

  [Other Info]

  ipu6-drivers/oracular is used in linux/oracular and linux-
  oem-6.11/noble, and ipu6-drivers/noble is used in linux/noble, linux-
  oem-6.8/noble and linux-hwe-6.8/jammy. The Noble SRU is only to
  satisfy compiling ipu6-drivers/noble against linux-oem-6.11/noble, but
  that's not how linux-modules-ipu6-oem-24.04b is built.
