The video drvdata should be set before the video device is registered,
otherwise video_drvdata() may return NULL in the open() file ops, and led
to oops.

Merge tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

Pull ordered workqueue creation updates from Tejun Heo:
"For historical reasons, unbound workqueues with max concurrency limit
of 1 are considered ordered, even though the concurrency limit hasn't
been system-wide for a long time.

This creates ambiguity around whether ordered execution is actually
required for correctness, which was actually confusing for e.g. btrfs
(btrfs updates are being routed through the btrfs tree).

There aren't that many users in the tree which use the combination and
there are pending improvements to unbound workqueue affinity handling
which will make inadvertent use of ordered workqueue a bigger loss.

This clarifies the situation for most of them by updating the ones
which require ordered execution to use alloc_ordered_workqueue().

There are some conversions being routed through subsystem-specific
trees and likely a few stragglers. Once they're all converted,
workqueue can trigger a warning on unbound + @max_active==1 usages and
eventually drop the implicit ordered behavior"

media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues

BACKGROUND
==========

When multiple work items are queued to a workqueue, their execution order
doesn't match the queueing order. They may get executed in any order and
simultaneously. When fully serialized execution - one by one in the
queueing order - is needed, an ordered workqueue should be used which can
be created with alloc_ordered_workqueue().

However, alloc_ordered_workqueue() was a later addition. Before it, an
ordered workqueue could be obtained by creating an UNBOUND workqueue with
@max_active==1. This originally was an implementation side-effect which was
broken by 4c16bd327c74 ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered"). Because there were users that depended on the ordered execution,
5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered")
made workqueue allocation path to implicitly promote UNBOUND workqueues w/
@max_active==1 to ordered workqueues.

While this has worked okay, overloading the UNBOUND allocation interface
this way creates other issues. It's difficult to tell whether a given
workqueue actually needs to be ordered and users that legitimately want a
min concurrency level wq unexpectedly gets an ordered one instead. With
planned UNBOUND workqueue updates to improve execution locality and more
prevalence of chiplet designs which can benefit from such improvements,
this isn't a state we wanna be in forever.

This patch series audits all callsites that create an UNBOUND workqueue w/
@max_active==1 and converts them to alloc_ordered_workqueue() as necessary.

WHAT TO LOOK FOR
================

The conversions are from

alloc_workqueue(WQ_UNBOUND | flags, 1, args..)

to

alloc_ordered_workqueue(flags, args...)

which don't cause any functional changes. If you know that fully ordered
execution is not necessary, please let me know. I'll drop the conversion
and instead add a comment noting the fact to reduce confusion while
conversion is in progress.

If you aren't fully sure, it's completely fine to let the conversion
through. The behavior will stay exactly the same and we can always
reconsider later.

As there are follow-up workqueue core changes, I'd really appreciate if the
patch can be routed through the workqueue tree w/ your acks. Thanks.
