Description of problem:
before F15, I could do this
cryptsetup status luks-${UUID}
if [ $? = 0 ]; then
        echo "Device already unlocked"
else
        echo "need to unlock device"
        cryptsetup luksOpen /dev/BANANA luks-${UUID}
fi

But since I installed F15 x86_64 on this box, cryptsetup status always has a return code of 0

Version-Release number of selected component (if applicable):
cryptsetup-luks-1.2.0-2.fc15.x86_64

How reproducible:
always

Steps to Reproduce:
[root@karhu ~]# cryptsetup status luks-SOMETHING
/dev/mapper/luks-SOMETHING is inactive.
[root@karhu ~]# echo $?
0
[root@karhu ~]# cryptsetup luksOpen /dev/BANANA luks-SOMETHING
Enter passphrase for /dev/BANANA: 
[root@karhu ~]# cryptsetup status luks-SOMETHING
/dev/mapper/luks-SOMETHING is active.
  type:  LUKS1
  cipher:  aes-cbc-essiv:sha256
  keysize: 256 bits
  device:  /dev/BANANA
  offset:  2056 sectors
  size:    104855544 sectors
  mode:    read/write
[root@karhu ~]# echo $?
0
  
Actual results:
exit code is 0 also when device is still locked

Expected results:
exit code 0 only when device is unlocked

Additional info:
obviously BANANA and SOMETHING is me replacing the UUID and device path by hand for the bug report
