From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
To fix a build error in drivers/scsi/lpfc/lpfc_sli.c when
CONFIG_CPU_FREQ is not set/enabled, add a stub function for
get_cpu_idle_time() in <linux/cpufreq.h>.
../drivers/scsi/lpfc/lpfc_sli.c: In function ‘lpfc_init_idle_stat_hb’:
../drivers/scsi/lpfc/lpfc_sli.c:7330:26: error: implicit declaration of function ‘get_cpu_idle_time’; did you mean ‘set_cpu_active’? [-Werror=implicit-function-declaration]
idle_stat->prev_idle = get_cpu_idle_time(i, &wall, 1);
