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") Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203997 Signed-off-by: Matias Karhumaa <matias.karhumaa@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
