instead of manually stashing the data pointer into parent directory inode's
->i_private, just pass it to debugfs_create_file_aux() so that it can
be extracted without that insane chasing through ->d_parent.

1) unbalanced debugfs_file_get(). Not needed in the first place -
file_operations are accessed only via debugfs_create_file(), so
debugfs wrappers will take care of that itself.
2) kmalloc() for a buffer used only for duration of a function is not
a problem, but for a buffer no longer than 16 bytes?
3) strstr() is for finding substrings; for finding a character there's
strchr().

When debugfs file has been created by debugfs_create_file_unsafe(),
we do need the file_operations methods to use debugfs_file_{get,put}()
to prevent concurrent removal; for files created by debugfs_create_file()
that is done in the wrappers that call underlying methods, so there's
no point whatsoever duplicating that in the underlying methods themselves.

Currently, there's really only one core callback for drivers, which is
probe().
Now, this isn't entirely true, since there is also the drop() callback of
the driver type (serving as the driver's private data), which is returned
by probe() and is dropped in remove().
On the C side remove() mainly serves two purposes:
(1) Tear down the device that is operated by the driver, e.g. call bus
specific functions, write I/O memory to reset the device, etc.
(2) Free the resources that have been allocated by a driver for a
specific device.
The drop() callback mentioned above is intended to cover (2) as the Rust
idiomatic way.
However, it is partially insufficient and inefficient to cover (1)
properly, since drop() can't be called with additional arguments, such as
the reference to the corresponding device that has the correct device
context, i.e. the Core device context.
This makes it inefficient (but not impossible) to access device
resources, e.g. to write device registers, and impossible to call device
methods, which are only accessible under the Core device context.
In order to solve this, add an additional callback for (1), which we
call unbind().
The reason for calling it unbind() is that, unlike remove(), it is *only*
meant to be used to perform teardown operations on the device (1), but
*not* to release resources (2).

Implementing if-conditions inside for_each_x() macros requires some
thinking to avoid side effects in the calling code. Resulting code
may look somewhat awkward, and there are couple of different ways it is
usually done.
Standardizing this to one way can help making it more obvious for a code
reader and writer. The newly added for_each_if() is a way to achieve this.
Use for_each_if() to make these macros look like many others which
should in the long run help reading the code.

- `inner` points to a `miscdevice` registered via `misc_register`.
- This registration stays valid for the entire lifetime of the object.
- Deregistration is guaranteed on `Drop`, via `misc_deregister`.

So far Devres uses an inner memory allocation and reference count, i.e.
an inner Arc, in order to ensure that the devres callback can't run into
a use-after-free in case where the Devres object is dropped while the
devres callback runs concurrently.
Instead, use a completion in order to avoid a potential UAF: In
Devres::drop(), if we detect that we can't remove the devres action
anymore, we wait for the completion that is completed from the devres
callback. If, in turn, we were able to successfully remove the devres
action, we can just go ahead.
This, again, allows us to get rid of the internal Arc, and instead let
Devres consume an `impl PinInit<T, E>` in order to return an
`impl PinInit<Devres<T>, E>`, which enables us to get away with less
memory allocations.
Additionally, having the resulting explicit synchronization in
Devres::drop() prevents potential subtle undesired side effects of the
devres callback dropping the final Arc reference asynchronously within
the devres callback.

Replace Devres::new_foreign_owned() with devres::register().
The current implementation of Devres::new_foreign_owned() creates a full
Devres container instance, including the internal Revocable and
completion.
However, none of that is necessary for the intended use of giving full
ownership of an object to devres and getting it dropped once the given
device is unbound.
Hence, implement devres::register(), which is limited to consume the
given data, wrap it in a KBox and drop the KBox once the given device is
unbound, without any other synchronization.

iterating over all of them.
In C, there is the function `fwnode_get_next_child_node` for iteration
and the macro `fwnode_for_each_child_node` that helps with handling the
pointers. Instead of a macro, a native iterator is used in Rust such
that regular for-loops can be used.

We need the driver-core fixes that are in 6.16-rc3 into here as well
to build on top of.

Pull i2c fixes from Wolfram Sang:
- subsystem: convert drivers to use recent callbacks of struct
i2c_algorithm A typical after-rc1 cleanup, which I couldn't send in
time for rc2
- tegra: fix YAML conversion of device tree bindings
- k1: re-add a check which got lost during upstreaming
* tag 'i2c-for-6.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: k1: check for transfer error
i2c: use inclusive callbacks in struct i2c_algorithm

Pull x86 fixes from Borislav Petkov:
- Make sure the array tracking which kernel text positions need to be
alternatives-patched doesn't get mishandled by out-of-order
modifications, leading to it overflowing and causing page faults when
patching
- Avoid an infinite loop when early code does a ranged TLB invalidation
before the broadcast TLB invalidation count of how many pages it can
flush, has been read from CPUID
- Fix a CONFIG_MODULES typo
- Disable broadcast TLB invalidation when PTI is enabled to avoid an
overflow of the bitmap tracking dynamic ASIDs which need to be
flushed when the kernel switches between the user and kernel address
space
- Handle the case of a CPU going offline and thus reporting zeroes when
reading top-level events in the resctrl code
* tag 'x86_urgent_for_v6.16_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/alternatives: Fix int3 handling failure from broken text_poke array
x86/mm: Fix early boot use of INVPLGB
x86/its: Fix an ifdef typo in its_alloc()
x86/mm: Disable INVLPGB when PTI is enabled
x86,fs/resctrl: Remove inappropriate references to cacheinfo in the resctrl subsystem

Pull irq fixes from Borislav Petkov:
- Fix missing prototypes warnings
- Properly initialize work context when allocating it
- Remove a method tracking when managed interrupts are suspended during
hotplug, in favor of the code using a IRQ disable depth tracking now,
and have interrupts get properly enabled again on restore
- Make sure multiple CPUs getting hotplugged don't cause wrong tracking
of the managed IRQ disable depth
* tag 'irq_urgent_for_v6.16_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irqchip/ath79-misc: Fix missing prototypes warnings
genirq/irq_sim: Initialize work context pointers properly
genirq/cpuhotplug: Restore affinity even for suspended IRQ
genirq/cpuhotplug: Rebalance managed interrupts across multi-CPU hotplug
