kernel/smpboot.c:164:36: sparse: incorrect type in initializer (different ad

Hi Thomas,

FYI, there are new sparse warnings show up in

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git auto-latest
head:   e42942691c8262b7fe2a7b88577623082b988217
commit: f97f8f06a49febbc3cb3635172efbe64ddc79700 [23/37] smpboot: Provide infrastructure for percpu hotplug threads

All sparse warnings:
