Title:
[SRU] Failed to build against linux >= 6.15
Status in broadcom-sta package in Ubuntu:

Bug description:
[SRU Justification]
[ Impact ]
Failed to build against kernel v6.15-rc1.
[ Test Plan ]
0. Install kernels >= v6.15
- mainline v6.15-rcX kernels from https://kernel.ubuntu.com/mainline, or
- linux-oem-6.17/noble
1. Install broadcom-sta-dkms from noble -proposed pocket
2. The dkms should rebuild itself against the running kernel automatically;
if not rebuild them manually with:
$ sudo dkms install --force broadcom-sta/6.30.223.271 -k $(uname
-r)
3. Reboot to load the kernel module
4. The wl module should be loaded automatically and wireless lan should be
usable as before.
[ Where problems could occur ]
This doesn't affect the rest part of the system, and it doesn't
introduce functional changes.
[ Other Info ]
This affects series with kernels >= 6.15. Nominate Noble.
Kernels >= 6.15 will not be introduced in Plucky.
========== original bug report ==========
1. EXTRA_*FLAGS has been deprecated for a while and is then removed in
v6.15-rc1 commit e966ad0edd005 ("kbuild: remove EXTRA_*FLAGS
support")， which results in following errors:
# CC [M] src/wl/sys/wl_linux.o
src/shared/linux_osl.c:23:10: fatal error: typedefs.h: No such file or
directory
23 | #include <typedefs.h>

compilation terminated.

2. `del_timer{,_sync}` have been redirected to `timer_delete{,_sync}`
since v6.2-rc1 and they are now removed in v6.15-rc1 commit
8fa7292fee5c5 ("treewide: Switch/rename to timer_delete[_sync]()"):
# CC [M] src/wl/sys/wl_linux.o

3. MODULE_DESCRIPTION is now a mandatory meta info for a module since
v6.15-rc1 commit 6c6c1fc09de35 ("modpost: require a
