media: start work to remove wait_prepare/finish callbacks
This patch series makes one change to videobuf2-core.c in vb2_thread()
where wait_prepare/finish was also called. That was missed in the
previous commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL"), but that is needed before we can start removing the
vb2_ops_wait_prepare/finish callbacks from drivers.
The next 9 patches drop the vb2_ops_wait_prepare/finish callbacks
from the various drivers in the media subsystem.
After this there are some V4L2 drivers in other subsystems (gadget,
input, staging) that need this change as well, but I'll start on that
when this series is merged.
There are also a few drivers that set the wait_prepare/finish callbacks
to their own implementation. Those need work as well.
Since this series touches on almost all V4L2 drivers, it is sent to
a lot of people.
Regards,
Hans
