During hibernation or restoration, freeze_secondary_cpus checks num_online_cpus via BUG_ON, and the subsequent save_processor_state also does the checking with WARN_ON. So remove the unnecessary checking in save_processor_state. Signed-off-by: Song Shuai <songshuaishuai@tinylab.org> --- arch/xtensa/kernel/hibernate.c | 1 - 1 file changed, 1 deletion(-)
