Subject: [PATCH 06/14] fscrypt: don't special-case EOPNOTSUPP from fscrypt_get_encryption_info()

From: Eric Biggers <ebiggers@...gle.com>

In fscrypt_setup_filename(), remove the unnecessary check for
fscrypt_get_encryption_info() returning EOPNOTSUPP.  There's no reason
to handle this error differently from any other.  I think there may have
been some confusion because the "notsupp" version of
fscrypt_get_encryption_info() returns EOPNOTSUPP -- but that's not
applicable from inside fs/crypto/.
