From: Jiri Bohac <jbo...@suse.cz>
commit 19d8e9149c27b689c6224f5c84b96a159342195a upstream.
Both pstore_compress() and decompress_record() use a mistyped config
option name ("PSTORE_COMPRESSION" instead of "PSTORE_COMPRESS"). As
a result compression and decompression of pstore records was always
disabled.
Use the correct config option name.
