Looks like this patch causes the following warnings:

DSI: omapdss DSI error: Failed to receive BTA
DSI: omapdss DSI error: bta sync failed
DSI: omapdss DSI error: vc(0) busy when trying to config for VP
DSI: omapdss DSI error: Failed to receive BTA
DSI: omapdss DSI error: bta sync failed
DSI: omapdss DSI error: vc(0) busy when trying to config for VP
DSI: omapdss DSI error: Failed to receive BTA
DSI: omapdss DSI error: bta sync failed
DSI: omapdss DSI error: vc(0) busy when trying to config for VP
...

Any ideas? The display works for me despite the constant
warnings.

Regards,

Tony
