It sounds fine to me (even the ADV7180 patch). Unfortunately I do not have the

As suggested I moved the Video Buffer Input (VIP) of the STA2X11 board to the
videobuf2. This patch series is an RFC.
The first patch is just an update to the adv7180 because the VIP (the only
user) now use the control framework so query{g_|s_|ctrl} are not necessery.
The second patch adds a new
out any control. I add it to
inherit controls from adv7180.
