Laurent Pinchart 5755be5f15 media: v4l2-subdev: Rename .init_cfg() operation to .init_state()
The subdev .init_cfg() operation is affected by two issues:

- It has long been extended to initialize a whole v4l2_subdev_state
  instead of just a v4l2_subdev_pad_config, but its name has stuck
  around.

- Despite operating on a whole subdev state and not being directly
  exposed to the subdev users (either in-kernel or through the userspace
  API), .init_cfg() is categorized as a subdev pad operation.

This participates in making the subdev API confusing for new developers.
Fix it by renaming the operation to .init_state(), and make it a subdev
internal operation.

Laurent Pinchart 30d187cd74 media: renesas: vsp1: Fix references to pad config
V4L2 subdev operations have moved from operating on a
v4l2_subdev_pad_config to a v4l2_subdev_state a long time ago. Fix
remaining incorrect references to pad config in function and variable
names.

Sakari Ailus bc0e8d91fe media: v4l: subdev: Switch to stream-aware state functions
Switch all drivers accessing sub-device state to use the stream-aware
functions. We will soon remove the old ones.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.

Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

Laurent Pinchart 42d62b7e47 media: vsp1: Remove unbalanced .s_stream(0) calls
The VSP1 driver uses the subdev .s_stream() operation to stop WPF
instances, without a corresponding call to start them. The V4L2 subdev
core started warning about unbalanced .s_stream() calls in commit
009905ec50 ("media: v4l2-subdev: Document and enforce .s_stream()
requirements"), causing a regression with this driver.

Fix the problem by replacing the .s_stream() operation with an explicit
function call for WPF instances. This allows sharing an additional data
structure between RPF and WPF instances.

Fixes: 009905ec50 ("media: v4l2-subdev: Document and enforce .s_stream() requirements")
