[ Test case ]

Install the latest linux-6.17 kernel on Noble:

$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge

Install digimend-dkms:

$ sudo apt install digimend-dkms

Module built and installed successfully.

Load the modules:

$ sudo modprobe hid-kye
$ sudo modprobe hid-uclogic
$ sudo modprobe hid-polostar
$ sudo modprobe hid-viewsonic

Modules loaded successfully.

The same procedure can be repeated on linux-6.8 to test for possible
regressions.

[ Fix ]

Apply patches from digimend-dkms Questing release enabling 6.17

* debian/patches/support-linux-6.15.patch

[ Regression potential ]

We may experience regressions in systems that are using the digimend
drivers, especially with kernels >= 6.8 kernel.

     Importance: Undecided
         Status: New

** Affects: digimend-dkms (Ubuntu Noble)
