Subject: [PATCH 3.4 17/44] Bluetooth: Remove unused hci_le_ltk_reply()

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Syam Sidhardhan <s.syam@...sung.com>

commit e10b9969f217c948c5523045f44eba4d3a758ff0 upstream.

In this API, we were using sizeof operator for an array
given as function argument, which is invalid.
However this API is not used anywhere.
