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

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

From: Danny Kukawka <redacted>

commit cc1d3e032df53d83d0ca4d537d8eb67eb5b3e808 upstream.

Commit ba02fa37de80bea10d706f39f076dd848348320a disabled the
venc driver registration on OMAP4. Since the driver never gets
probed/initialised your get a dereferenceed NULL pointer if you
try to get info from /sys/kernel/debug/omapdss/venc

Return info message about disabled venc if venc_dump_regs() gets called.
