Mark: I must be missing something here. Why would this media controller API make things simpler? Based on what was presented at LPC, I don't understand this last part. -Pierre -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
