We did test new kernels with W=1, and the issue was captured by the bot, then bisected to this 2 years 7 months ago commit that was likely to introduce this issue initially. We have no intention of directly testing a very old commit, and we're sorry that the date info may cause some misunderstanding.
This can be reproduced by allyesconfig build on v6.6 with W=1:
$ git checkout v6.6 HEAD is now at ffc253263a13 Linux 6.6
$ make ARCH=x86_64 allyesconfig
$ make W=1 ARCH=x86_64 drivers/comedi/drivers/tests/ni_routes_test.o ...
