Subject: pstore: Rename "pstore_lock" to "psinfo_lock"
Git-commit: c30b20cd96a7a08e77c12cb3326c6fd801f7fe87
Patch-mainline: v5.8
References: jsc#SLE-16304
Acked-by: Jiri Bohac <jbohac@suse.cz>
The name "pstore_lock" sounds very global, but it is only supposed to be
used for managing changes to "psinfo", so rename it accordingly.
