Subject: f2fs: Show casefolding support only when supported
From: Daniel Rosenberg <drosen@google.com>
commit 39307f8ee3539478c28e71b4909b5b028cce14b1 upstream.
The casefolding feature is only supported when CONFIG_UNICODE is set.
This modifies the feature list f2fs presents under sysfs accordingly.
Fixes: 5aba54302a46 ("f2fs: include charset encoding information in the superblock")
