Hi all, After merging the net-next tree, today's linux-next build (sparc64 defconfig) produced this warning: drivers/net/ethernet/intel/e1000e/netdev.c:137:13: warning: 'e1000e_check_me' defined but not used [-Wunused-function] static bool e1000e_check_me(u16 device_id) ^~~~~~~~~~~~~~~ Introduced by commit e086ba2fccda ("e1000e: disable s0ix entry and exit flows for ME systems") CONFIG_PM_SLEEP is not set for this build. -- Cheers, Stephen Rothwell
