Subject: OMAPDSS: VENC: fix NULL pointer dereference in DSS2 VENC sysfs debug
attr on OMAP4
From: Danny Kukawka <[email protected]>
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.
