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

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

From: Michael Krufky <mkrufky@linuxtv.org>

commit 3be5bb71fbf18f83cb88b54a62a78e03e5a4f30a upstream.

Remove unnecessary register access in mxl111sf_ep6_streaming_ctrl()

This code breaks driver operation in kernel 3.3 and later, although
it works properly in 3.2  Disable register access to 0x12 for now.
