KEYS: Fix variable uninitialisation warnings
Fix variable uninitialisation warnings introduced in:
commit 8bbf4976b59fc9fc2861e79cab7beb3f6d647640
Author: David Howells <dhowells@redhat.com>
Date: Fri Nov 14 10:39:14 2008 +1100
KEYS: Alter use of key instantiation link-to-keyring argument
As:
security/keys/keyctl.c: In function 'keyctl_negate_key':
security/keys/keyctl.c:976: warning: 'dest_keyring' may be used uninitialized in this function
security/keys/keyctl.c: In function 'keyctl_instantiate_key':
security/keys/keyctl.c:898: warning: 'dest_keyring' may be used uninitialized in this function
Some versions of gcc notice that get_instantiation_key() doesn't always set
*_dest_keyring, but fail to observe that if this happens then *_dest_keyring
will not be read by the caller.
