CVE: NA

--------------------------------

This reverts commit 1f9fa07b.

Commit 2fe0e281f7ad witch merged by LTS (cifs: fix double free race
when mount fails in cifs_get_root()) fixes a double free. However,
the previous patch d17abdf7 is not merged. There is no such
issue on 5.10 because it will return after cifs_cleanup_volume_info().

Since merge this patch, cifs_cleanup_volume_info() is skipped, leading
to a memory leak.
