This patch generates warnings that e1000e_s0ix_entry_flow and e1000e_s0ix_exit_flow are defined but not used [-Wunused-function] when CONFIG_PM_SLEEP is not defined. The warnings were called out by Intel's 0-DAY kernel test infrastructure after this patch was merged into the dev-queue branch of Jeff's next-queue tree, so any fix for the warnings should include the tag " Reported-by: kbuild test robot <l...@intel.com>".
