Subject: [PATCH stable 5.4] PM: wakeup: Show statistics for deleted wakeup sources again

From: zhuguangqing <zhuguangqing@...omi.com>

commit e976eb4b91e906f20ec25b20c152d53c472fc3fd upstream

After commit 00ee22c28915 (PM / wakeup: Use seq_open() to show wakeup
stats), print_wakeup_source_stats(m, &deleted_ws) is not called from
wakeup_sources_stats_seq_show() any more.

Because deleted_ws is one of the wakeup sources, it should be shown
too, so add it to the end of all other wakeup sources.
