[PATCH 4.19 207/247] pstore: Fix typo in compression option name

From: Greg Kroah-Hartman
Date: Mon Mar 01 2021 - 16:20:07 EST


From: Jiri Bohac <jbohac@xxxxxxx>

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.
