In Linux v6.10, the v4l2-subdev callbacks 'g_dv_timings' and
's_dv_timings' were moved from the v4l2_subdev_video_ops structure to
the v4l2_subdev_pad_ops structure. Fix the build for Linux v6.10 by
using conftest to determine which structure is used for these callbacks.

Add the check to see if the device is already in use or not,
while calling s_ctrl by multiple user apps on the same video node.
Here ,The "vb2_is_busy" function checks if the queue represented
by the vb2_queue instance is busy by checking if there are any
buffers in the active queue.If there are any buffers in the active queue,
it means that they are currently being processed by the device driver,
and the queue is considered busy.

For Linux v6.8, the function strlcpy() has been removed. The function
strscpy() was added in Linux v4.3 and has been preferred over strlcpy().
See upstream Linux commit 30035e45753b ("string: provide strscpy()") for
more details. The Linux checkpatch.pl script warns against using
strlcpy().
The function strscpy() takes the same arguments as strlcpy(), but
returns a type of ssize_t instead of size_t. Update the drivers to use
strscpy() instead of strlcpy().

The earlier porting of the driver for Linux 6.6 is not
matching with the previous kernel implementation.
Few V4L2 APIs have been deprecated from Linux 6.6. and
added the new APIs.
Use the correct API available from Linux6.6 for the
replacement as the previous supported kernel APIs.
For reference, the changes in core kernels are:
The device argument is added in the API v4l2_async_nf_init() with
commit b8ec754ae4c5 ("media: v4l: async: Set v4l2_device and subdev

The API is removed with commit bda8953e8c3e ("media: v4l: async: Drop
