Hi,
osmocom-dahdi-dkms (and probably dahdi-dkms as well) fails to build the
module(s) for Linux 6.15 in experimental:
DKMS (dkms-3.2.0) make.log for osmocom-dahdi/0.0~git20241003.b2ea348 for kernel 6.15-rc7-amd64 (x86_64)

https://github.com/torvalds/linux/commit/9b13df3fb64ee95e2397585404e442afee2c7d4f
the backwards compatibility support wrappers have been removed in
v6.15-rc1 "treewide: Switch/rename to timer_delete[_sync]()"
