[v7,0/8] v4l: subdev active state

Message

Hi,

v7 of the subdev active state series. v6 can be found from:

https://lore.kernel.org/all/[e-mail]/

Only minor changes since v6:

- Use v4l2_subdev_get_pad_format in v4l2_subdev_get_fmt
- Update doc wrt. using v4l2_subdev_lock_and_return_state
- Rename v4l2_subdev_get_try_* to v4l2_subdev_get_pad_*, and add helper
  macros to keep the old func names working

Hans suggested changing v4l2_subdev_get_fmt() to
v4l2_subdev_pad_op_get_fmt() (or similar). I haven't made that change as
v4l2_subdev_get_fmt() can be used for other purposes than a pad op
function, but I'm not against the change if other people support the
change. It is an easy rename to do later.
