 - fix VIDIOC_DQEVENT ioctl handling for 32-bit userspace with a 64-bit
   kernel

 - regression fix for videobuf2 core

 - fix for CEC core when handling non-block transmit

 - hi846: fix a clang warning

* tag 'media/v5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  media: hi846: remove the of_match_ptr macro
  media: hi846: include property.h instead of of_graph.h
  media: cec: copy sequence field for the reply
  media: videobuf2-dma-sg: Fix buf->vb NULL pointer dereference
  media: v4l2-core: fix VIDIOC_DQEVENT handling on non-x86

Similar to other drivers, this should fix a Clang compilar warning when
building without CONFIG_OF in which case of_match_ptr() is NULL and
the const struct we would use otherwise is unused.

Pull more ACPI updates from Rafael Wysocki:
 "These add support for a new ACPI device configuration object called
  _DSC, fix some issues including one recent regression, add two new
  items to quirk lists and clean up assorted pieces of code.

  Specifics:

   - Add support for new ACPI device configuration object called _DSC
     ("Deepest State for Configuration") to allow certain devices to be
     probed without changing their power states, document it and make
     two drivers use it (Sakari Ailus, Rajmohan Mani).

   - Fix device wakeup power reference counting broken recently by
     mistake (Rafael Wysocki).

   - Drop unused symbol and macros depending on it from acgcc.h (Rafael
     Wysocki).

   - Add HP ZHAN 66 Pro to the "no EC wakeup" quirk list (Binbin Zhou).

   - Add Xiaomi Mi Pad 2 to the backlight quirk list and drop an unused
     piece of data from all of the list entries (Hans de Goede).

   - Fix register read accesses handling in the Intel PMIC operation
     region driver (Hans de Goede).

   - Clean up static variables initialization in the EC driver
     (wangzhitong)"

When the reply for a non-blocking transmit arrives, the sequence
field for that reply was never filled in, so userspace would have no
way of associating the reply to the original transmit.

Copy the sequence field to ensure that this is now possible.

Commit a4b83deb3e76 ("media: videobuf2: rework vb2_mem_ops API")
added a new vb member to struct vb2_dma_sg_buf, but it only added
code setting this to the vb2_dma_sg_alloc() function and not to the
vb2_dma_sg_get_userptr() and vb2_dma_sg_attach_dmabuf() which also
create vb2_dma_sg_buf objects.

This is causing a crash due to a NULL pointer deref when using
libcamera on devices with an Intel IPU3 (qcam app).

Fix these crashes by assigning buf->vb in the other 2 functions too,
note libcamera tests the vb2_dma_sg_get_userptr() path, the change
to the vb2_dma_sg_attach_dmabuf() path is untested.

My previous bugfix addressed an API inconsistency found by syzbot,
and it correctly fixed the issue on x86-64 machines, which now behave
correctly for both native and compat tasks.

Unfortunately, John found that the patch broke compat mode on all other
architectures, as they can no longer rely on the VIDIOC_DQEVENT_TIME32
code from the native handler as a fallback in the compat code.

The best way I can see for addressing this is to generalize the
VIDIOC_DQEVENT32_TIME32 code from x86 and use that for all architectures,
leaving only the VIDIOC_DQEVENT32 variant as x86 specific. The original
code was trying to be clever and use the same conversion helper for native
32-bit code and compat mode, but that turned out to be too obscure so
even I missed that bit I had introduced myself when I made the fix.

When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.

Replace kernel.h inclusion with the list of what is really being used.

Pull char/misc driver updates from Greg KH:
 "Here is the big set of char and misc and other tiny driver subsystem
  updates for 5.16-rc1.

  Loads of things in here, all of which have been in linux-next for a
  while with no reported problems (except for one called out below.)

  Included are:

   - habanana labs driver updates, including dma_buf usage, reviewed and
     acked by the dma_buf maintainers

   - iio driver update (going through this tree not staging as they
     really do not belong going through that tree anymore)

   - counter driver updates

   - hwmon driver updates that the counter drivers needed, acked by the
     hwmon maintainer

   - xillybus driver updates

   - binder driver updates

   - extcon driver updates

   - dma_buf module namespaces added (will cause a build error in arm64
     for allmodconfig, but that change is on its way through the drm
     tree)

   - lkdtm driver updates

   - pvpanic driver updates

   - phy driver updates

   - virt acrn and nitr_enclaves driver updates

   - smaller char and misc driver updates"
