From fe39c7b2dacf7fd4dcddc26704d01315ab92b7cb Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 27 Feb 2014 16:00:28 -0800 Subject: Bluetooth: Use __le64 type for LE random numbers The random numbers in Bluetooth Low Energy are 64-bit numbers and should also be little endian since the HCI specification is little endian. Change the whole Low Energy pairing to use __le64 instead of a byte array.
