Subject: fscrypt: don't check for ENOKEY from fscrypt_get_encryption_info()
X-Git-Tag: v5.6-rc1~155^2~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b1ada55b905f306411f481df52b586cc8a407b8;p=thirdparty%2Flinux.git

fscrypt: don't check for ENOKEY from fscrypt_get_encryption_info()

fscrypt_get_encryption_info() returns 0 if the encryption key is
unavailable; it never returns ENOKEY.  So remove checks for ENOKEY.
