media: staging: Drop starfive-camss from staging

2026-03-11T00:05:30+00:00

The starfive-camss driver is no longer being worked upon for destaging,
as confirmed by the maintainer, so drop it.

Merge tag 'staging-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2024-11-29T19:36:13+00:00

Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver changes for 6.13-rc1.

  Lots of changes this merge cycle, drivers removed and drivers added.
  Highlights include:

   - removals of the following staging drivers due to no forward
     progress and no one having either the hardware or the time/energy
     to deal with them anymore:
       - fieldbus
       - gdm724x
       - olpc_dcon
       - rtl8712
       - rts5208
       - vt6655
       - vt6656
     If anyone has this hardware and wants to work on the drivers, it
     can be an easy revert to get them back.

   - addition of the gpib driver subsystem. Lots of drivers for really
     old and semi-old interfaces to lab equipments. We expect lots of
     churn in these drivers as they get cleaned up to "working" order.

     These were added at the request of a user and the maintainer/author
     of them is helping out with the effort

   - loads and loads of tiny coding style cleanups for almost all
     staging drivers. Too many to list, see the shortlog for details.

  All of these have been in linux-next for a very long time with no
  reported issues"

staging: media: drop vb2_ops_wait_prepare/finish

2024-10-28T08:20:09+00:00

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.

Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.

This simplifies the code and this is a step towards the goal of deleting
these callbacks.

staging: Switch back to struct platform_driver::remove()

2024-10-09T09:54:53+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all staging drivers to use .remove(), with the eventual goal to
drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

The code to select isp_dev->formats[] is overly complicated.  We can
just use the "pad" as the index.  This will making adding new pads
easier in future patches.  No functional change.

media: staging: media: starfive: camss: Convert to platform remove callback returning void

2024-04-08T11:48:18+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
