[15:21] <LocutusOfBorg> hello, wrt ddcci-driver-linux, I found the clue
[15:21] <LocutusOfBorg> Makefile:228: 'SUBDIRS' will be removed after Linux 5.3
[15:21] <LocutusOfBorg> Makefile:229: Please use 'M=' or 'KBUILD_EXTMOD' instead
[15:21] <LocutusOfBorg> Makefile:230: [15:21] <LocutusOfBorg> ERROR: "devm_backlight_device_register" [/var/lib/dkms/ddcci/0.3.2/build/ddcci-backlight/ddcci-backlight.ko] undefined!
[15:21] <LocutusOfBorg> according to kernel build log backlight modules are not built in new kernel...
[15:45] <LocutusOfBorg> sforshee, ^^
[15:45] <LocutusOfBorg> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1837073
[15:46] <LocutusOfBorg>      - [Config] CONFIG_BACKLIGHT_CLASS_DEVICE=n on s390x
[15:46] <LocutusOfBorg> this breaks dkms on s390x for that package... re-enable or hint the testsuite?
[15:47] <sforshee> LocutusOfBorg: it's never actually worked for s390, the difference is that kbuild has changed to make the missing symbols an error instead of a warning
[15:47] <sforshee> so likely this and other packages should be updated to skip the build when installed on s390
[15:48] <sforshee> there are some others which depend on acpi which fail similarly
[15:48] <LocutusOfBorg> sforshee, I assigned the bug to you... can you please make the package migrate then? :)
[15:48] <LocutusOfBorg> at least if we hint, we can give the hint a comment with a bug number
[15:49] <sforshee> ack, I cannot personally make it migrate but I will follow up on it
[15:49] <LocutusOfBorg> apw might be the best person to hint...
[15:50] <LocutusOfBorg> asked on release channel
[15:50] <LocutusOfBorg> lets see
