#     Bluetooth: Fix faulty expression for minimum encryption key size check
#     
#     Fix minimum encryption key size check so that HCI_MIN_ENC_KEY_SIZE is
#     also allowed as stated in the comment.
#     
#     This bug caused connection problems with devices having maximum
#     encryption key size of 7 octets (56-bit).
#     
#     Fixes: 693cd8ce3f88 ("Bluetooth: Fix regression with minimum encryption key size alignment")
