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.

media: v4l: subdev: Rename sub-device state information access functions Rename the sub-devices state information access functions, removing "_stream" from them and replacing "format" by "ffmt". This makes them shorter and so more convenient to use. No other sets of functions will be needed to access this information.

media: i2c: ds90ub913: Fix use of uninitialized variables smatch reports some uninitialized variables: drivers/media/i2c/ds90ub913.c:481 ub913_log_status() error: uninitialized symbol 'v1'. drivers/media/i2c/ds90ub913.c:481 ub913_log_status() error: uninitialized symbol 'v2'. These are used only for printing debug information, and the use of an uninitialized variable only happens if an i2c transaction has failed, which will print an error. Thus, fix the errors just by initializing the variables to 0.

media: i2c: ds90ub9x3: Fix sub-device matching Commit 1029939b3782 ("media: v4l: async: Simplify async sub-device fwnode matching") recently changed how async sub-device matching works. This breaks the UB9x3 drivers, as they set the subdev.fwnode to an endpoint. Afaiu, the fix is simply to not set subdev.fwnode at all.

media: v4l: async: Set v4l2_device and subdev in async notifier init Set the v4l2_device already in async notifier init, so struct device related to it will be available before the notifier is registered. This requires separating notifier initialisation into two functions, one that takes v4l2_device as its argument, v4l2_async_nf_init and v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the notifier will use a single function, v4l2_async_nf_register. This is done in order to make struct device available earlier, during construction of the async connections, for sensible debug prints.

media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection Rename v4l2_async_subdev as v4l2_async_connection, in order to differentiate between the sub-devices and their connections: one sub-device can have many connections but the V4L2 async framework has so far allowed just a single one. Connections in this context will later translate into either MC ancillary or data links. This patch prepares changing that relation by changing existing users of v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices themselves will not be needed anymore Additionally, __v4l2_async_nf_add_subdev() has been renamed __v4l2_async_nf_add_connection().
