Subject: [PATCH 3.12 026/206] Bluetooth: Fix endianess issue in the ath3k driver

From: Peng Chen <pengchen@....qualcomm.com>

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

===============

commit b9e2535acad8f52a17e2aa843d45a6b756b59592 upstream.

The version is always in little endian format. This patch makes the
driver work on both little and big endian CPUs.
