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)

del_timer_sync() has been renamed to timer_delete_sync() in v6.2-rc1
"timers: Rename del_timer_sync() to timer_delete_sync()" 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]()" https://github.com/torvalds/linux/commit/8fa7292fee5c5240402371ea89ab285ec856c916
