2012-05-14[media] v4l: Improve sub-device documentation for pad opsSakari Ailus1-0/+9

2012-05-07[media] v4l2-event: Add v4l2_subscribed_event_opsHans de Goede1-7/+21
Just like with ctrl events, drivers may want to get called back on listener add / remove for other event types too. Rather then special casing all of this in subscribe / unsubscribe event it is better to use ops for this.

The ability to force the encoder or decoder chip was broken by commit 0ab6e1c38d80ab586e3a1ca9e71844131d9f51dc in February 2009. As nobody complained for over 2 years, I take it that these parameters were no longer used so we can simply drop them.
