Subject: cpuidle: header file stubs must be "static inline"
References: jsc#SLE-11312
Patch-Mainline: v5.4-rc1
Git-commit: 7dcddef6f769d7e60691c732eb6d09cdb1d9df76


An x86_64 allmodconfig build produces these errors:

x86_64-linux-gnu-ld: kernel/sched/core.o: in function `cpuidle_poll_time':
core.c:(.text+0x230): multiple definition of `cpuidle_poll_time'; arch/x86/=
kernel/process.o:process.c:(.text+0xc0): first defined here

(and more)

Fixes: 259231a04561 ("cpuidle: add poll_limit_ns to cpuidle_device structure")
