media: m5mols: fix off-by-one loop termination error
The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.
Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.
But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.
And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:
drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()
Fix the loop ending condition.

ARM: SoC drivers for 6.3
As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

media: v4l2-subdev.c: clear stream field
Both userspace and kernelspace can pass structs with an uninitialized 'stream' field. Since the check_state() function checks for a non-zero stream field, suddenly these calls will fails with -EINVAL. So check in the wrapper functions in v4l2-subdev.c (which are used by both the kernel and userspace API) if V4L2_SUBDEV_FL_STREAMS is set, and if not, then zero the stream field. Currently no drivers set V4L2_SUBDEV_FL_STREAMS, so the stream field will always be set to 0. This patch might well be reverted in the future when streams support is fully enabled and we finalized the userspace API support for this feature.

IOMMU Updates for Linux v6.3:
Including:
- Consolidate iommu_map/unmap functions. There have been
blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.
- Retire the detach_dev() call-back in iommu_ops
- Arm SMMU updates from Will:
- Device-tree binding updates:
* Cater for three power domains on SM6375
* Document existing compatible strings for Qualcomm SoCs
* Tighten up clocks description for platform-specific compatible strings
- Enable Qualcomm workarounds for some additional platforms that need them
- Intel VT-d updates from Lu Baolu:
- Add Intel IOMMU performance monitoring support
- Set No Execute Enable bit in PASID table entry
- Two performance optimizations
- Fix PASID directory pointer coherency
- Fix missed rollbacks in error path
- Cleanups
- Apple t8110 DART support
- Exynos IOMMU:
- Implement better fault handling
- Error handling fixes
- Renesas IPMMU:
- Add device tree bindings for r8a779g0
- AMD IOMMU:
- Various fixes for handling on SNP-enabled systems and
handling of faults with unknown request-ids
- Cleanups and other small fixes
- Various other smaller fixes and cleanups

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

- Daniel Verkamp has contributed a memfd series ("mm/memfd: add
F_SEAL_EXEC") which permits the setting of the memfd execute bit at
memfd creation time, with the option of sealing the state of the X bit.
- Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset()
thread-safe for pmd unshare") which addresses a rare race condition
related to PMD unsharing.

Moola, Sidhartha Kumar and Lorenzo Stoakes
- Johannes Weiner has a series ("mm: push down lock_page_memcg()") which
does perform some memcg maintenance and cleanup work.

tree".

ARM: unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board files that was merged in linux-6.0, removing them for good. This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files. See commit |

media: imx: imx7-media-csi: Use V4L2 subdev active state
Use the V4L2 subdev active state API to store the active format. This simplifies the driver not only by dropping the state stored in the imx7_csi structure, but also by replacing the manual lock with the state lock. The is_streaming field is now protected by the active state lock, either explicitly in .s_stream(), where the active state is locked manually, or implicitly in .set_fmt(), which is called with the state locked.

The v4l2_subdev_format structure passed to the .get_fmt() subdev operation in imx7_csi_video_validate_fmt() isn't zeroed, which can cause undefined behaviour. Fix it.

media: imx: imx7-media-csi: Cleanup errors in imx7_csi_async_register()
It's good practice for functions to perform error cleanup internally when they fail, in order to not leave the device in a half-initialized state. Move the async notifier cleanup from the probe error path to the imx7_csi_async_register(), and drop the v4l2_async_nf_unregister() call as there is no error path after the async notifier gets registered.

When the siano device is plugged in, it may call the following functions
to initialize the device.
smsusb_probe()-->smsusb_init_device()-->smscore_start_device().
When smscore_start_device() gets failed, the function smsusb_term_device()
will be called and smsusb_device_t will be deallocated. Although we use
usb_kill_urb() in smsusb_stop_streaming() to cancel transfer requests
and wait for them to finish, the worker threads that are scheduled by
smsusb_onresponse() may be still running. As a result, the UAF bugs
could happen.
We add cancel_work_sync() in smsusb_stop_streaming() in order that the
worker threads could finish before the smsusb_device_t is deallocated.
