The use of state->CH_Ctrl[i].size in a shift operation implies that its
value can be as much as 32, but the state->CH_Ctrl[i].val array is only
25 in size. Bounds check the size before shifting and looping. Fixes
warnings seen with GCC 13:

dvb_net.h includes a bunch of core networking headers which increases
the number of objects rebuilt when we touch them. They are unnecessary
for the header itself and only one driver has an indirect dependency.
tveeprom.h includes if_packet to gain access to ETH_ALEN. This
is a bit of an overkill because if_packet.h pulls in skbuff.h.
The definition of ETH_ALEN is in the uAPI header, which is
very rarely touched, so switch to including that.
This results in roughly 250 fewer objects built when skbuff.h
is touched (6028 -> 5788).

Add a common keymap for the RC10/RC0 and RC20/RC-BT remotes used with
the Dreambox One and Dreambox Two DVB-S/T boxes. The maps are combined
since the IR codes do not conflict and both boxes have shipped with
both remote designs over time.
Both remote types can be programmed to control TVs, so include non-IR
keys that are used to switch-to or toggle the remote mode:
- DREAM in RC10/RC0 switches to (Dreambox) STB control mode
- TV in RC10/RC0 switches to TV control mode
- MODE in RC20/RC-BT toggles between STB/TV/BT control modes
In the RC20 keymap the Android MIC (voice search) key maps to KEY_HELP
and EXIT is mapped to KEY_ESC to replicate the go-backwards navigation
behaviour in the Android vendor OS that ships on Dreambox devices.

Before vb2_read is called, the owner must be set since vb2_read will
actually start streaming. If vb2_read returns an error and q->fileio is
NULL, then it failed to start streaming and the owner is set back to NULL.
When the vb2 start_streaming callback is called, it expects the owner
pointer to be set, and that wasn't the case in this particular situation.

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()

The new subdev state code has a possible deadlock scenario during link
validation when the pipeline contains subdevs that support state and
that do not support state.
The current code locks the states of the subdevs on both ends of the
link when starting the link validation, locking the sink side first,
then the source. If either (or both) of the subdevs does not support
state, nothing is done for that subdev at this point, and instead the
locking is handled the old way, i.e. the subdev's ops do the locking
internally.
The issue arises when the sink doesn't support state, but source does,
so the validation code locks the source for the duration of the
validation, and then the sink is locked only when the get_fmt op is
called. So lockdep sees the source locked first, then the sink.
Later, when the streaming is started, the sink's s_stream op is called,
which probably takes the subdev's lock. The op then calls the source's
s_stream, which takes the source's lock. So, the sink is locked first,
then the source.
Note that link validation and stream starting is not done at the same
time, so an actual deadlock should never happen. However, it's still a
clear bug.
Fix this by locking the subdev states only if both subdevs support
state. In other words, we have two scenarios:
1. Both subdevs support state. Lock sink first, then source, and keep
the locks while validating the link.
2. At least one of the subdevs do not support state. Take the lock only
for the duration of the operation (get_fmt or looking at the
routing), and release after the op is done.
Obviously 1. is better, as we have a more consistent view of the states
of the subdevs during validation. 2. is how it has been so far, so it's
no worse than this used to be.

The runtime suspend/resume functions are only referenced from the
dev_pm_ops, but they use the old SET_RUNTIME_PM_OPS() helper
that requires a __maybe_unused annotation to avoid a warning:
drivers/media/i2c/imx290.c:1082:12: error: unused function 'imx290_runtime_resume' [-Werror,-Wunused-function]
static int imx290_runtime_resume(struct device *dev)

drivers/media/i2c/imx290.c:1090:12: error: unused function 'imx290_runtime_suspend' [-Werror,-Wunused-function]
static int imx290_runtime_suspend(struct device *dev)
^
Convert this to the new RUNTIME_PM_OPS() helper that so this
is not required. To improve this further, also use the pm_ptr()
helper that lets the dev_pm_ops get dropped entirely when
CONFIG_PM is disabled.
A related mistake happened in the of_match_ptr() macro here, which
like SET_RUNTIME_PM_OPS() requires the match table to be marked
as __maybe_unused, though I could not reproduce building this without
CONFIG_OF. Remove the of_match_ptr() here as there is no point in
dropping the match table in configurations without CONFIG_OF.

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.

"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

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"

that there's a pending report that has a fix that is queued up - Linus ]

Pull ARM SoC boardfile updates from Arnd Bergmann
"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 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed.
The only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users"

There's no need to use threaded IRQs with the PXP, as the interrupt
handler doesn't need to sleep and doesn't perform any time-consuming
operation. Switch to regular IRQ handler.
This fixes lockups of the PXP noticed on i.MX7, where the PXP would stop
generating interrupts after a variable number of frames (from a few
dozens to a few hundreds). The root cause is however unknown.

Add pxp_read() and pxp_write() functions to wrap readl() and writel()
respectively. This can be useful for debugging register accesses.

The find_format() function looks up format information for a given pixel
format. It takes a v4l2_format pointer, but only uses the contained
pixel format value. To prepare it for being used by callers that don't
have v4l2_format, modify it to take the pixel format value directly.

Register a media device for the PXP, using the v4l2-mem2mem MC
infrastructure to populate the media graph. No media device operation is
implemented, the main use of the MC API is to allow consistent discovery
of media devices for userspace.

The v4l2_capability.bus_info field is set by the V4L2 core when left
empty by the .querycap() handler. This is the recommended practice, in
order to ensure bus_info coherence between drivers. Don't set it
manually.
