Subject: [PATCH 1/4] ARM: hibernate: remove WARN_ON in save_processor_state
Date:   Thu, 25 May 2023 10:55:52 +0800

Precedence: bulk

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.
