-Subject: [PATCH] Bluetooth: Check key sizes only when Secure Simple
- Pairing is enabled
-
-The encryption is only mandatory to be enforced when both sides are using
-Secure Simple Pairing and this means the key size check makes only sense
-in that case.
-
-On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
-optional and thus causing an issue if the key size check is not bound to
-using Secure Simple Pairing.
-
-Fixes: d5bb334a8e17 ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")
