media: i2c: ds90ub9x3: Fix extra fwnode_handle_put()

commit 60b45ece41c5632a3a3274115a401cb244180646 upstream.

The ub913 and ub953 drivers call fwnode_handle_put(priv->sd.fwnode) as
part of their remove process, and if the driver is removed multiple
times, eventually leads to put "overflow", possibly causing memory
corruption or crash.

The fwnode_handle_put() is a leftover from commit 905f88ccebb1 ("media:
i2c: ds90ub9x3: Fix sub-device matching"), which changed the code
related to the sd.fwnode, but missed removing these fwnode_handle_put()
calls.

Pull media updates from Mauro Carvalho Chehab:

- new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

- new Intel IVSC MEI drivers

- some Mediatek platform drivers were moved to a common location

- Intel atomisp2 driver is now working with the main ov2680 driver. Due
to that, the atomisp2 ov2680 staging one was removed

- the bttv driver was finally converted to videobuf2 framework. This
was the last one upstream using videobuf version 1 core. We'll likely
remove the old videobuf framework on 6.7

- lots of improvements at atomisp driver: it now works with normal I2C
sensors. Several compile-mode dependecies to select between ISP2400
and ISP2401 are now solved in runtime

- a new ipu-bridge logic was added to work with IVSC MEI drivers

- venus driver gained better support for new VPU versions

- the v4l core async framework has gained lots of improvements and
cleanups

- lots of other cleanups, improvements and driver fixes

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.

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().
