From 51beabdf624df14d0805b001d3f939629b70d9db Mon Sep 17 00:00:00 2001 From: Anderson Briglia <anderson.briglia@openbossa.org> Date: Mon, 19 Sep 2011 14:41:09 -0400 Subject: [PATCH] Bluetooth: Fix wrong memcpy size on LE start encryption This patch fixes wrong memcpy size when copying rand value to HCI_OP_LE_START_ENC command. The compiler pretends that the array parameter was declared as a pointer and sizeof reports the size of the pointer.
