snd_seq_oss_write() currently returns the raw load_patch() callback

That callback is documented as returning 0 on success and -errno on

report the number of user bytes consumed on success. Some in-tree

snd_usbmidi_standard_output() iterates output ports in ascending order
and drains each active port until the URB is full. On interfaces where
multiple USB-MIDI cables share one endpoint, sustained traffic on a
lower-numbered port can consume every refill before higher-numbered
ports are even examined.
That behavior dates back to the original implementation and still
applies with the current multi-URB output path. snd_usbmidi_do_output()
can refill several idle URBs in one pass, but each refill restarts the
scan at port 0, so a busy lower-numbered port can keep higher-numbered
ports from making progress at all.
Use ep->current_port as the starting point of the scan and advance it
after each URB fill. This keeps the existing packet formatting and
per-port state handling intact while preventing persistent starvation of
higher-numbered ports.

snd_pcm_ioctl_sync_ptr_x32() still handles incoming appl_ptr updates
differently from the other SYNC_PTR paths. The native handler and the
32-bit compat handler both pass appl_ptr through pcm_lib_apply_appl_ptr(),
but the x32 handler still writes control->appl_ptr directly.
That direct assignment skips the common appl_ptr validation against
runtime->boundary and also bypasses the substream ack() callback.
This makes the x32 ioctl path behave differently from the native and
compat32 cases, and it can miss the driver notification that explicit
appl_ptr synchronization relies on.
Use pcm_lib_apply_appl_ptr() for x32 too, so appl_ptr updates are
validated consistently and drivers relying on ack() notifications
see the same behavior.

Identified resume-probe race condition in kernel v7.0 with the commit
38fa29b01a ("i2c: designware: Combine the init functions"),but this
issue existed from the beginning though not detected.
The amdisp i2c device requires ISP to be in power-on state for probe
to succeed. To meet this requirement, this device is added to genpd
to control ISP power using runtime PM. The pm_runtime_get_sync() called
before i2c_dw_probe() triggers PM resume, which powers on ISP and also
invokes the amdisp i2c runtime resume before the probe completes resulting
in this race condition and a NULL dereferencing issue in v7.0
Fix this race condition by using the genpd APIs directly during probe:
- Call dev_pm_genpd_resume() to Power ON ISP before probe
- Call dev_pm_genpd_suspend() to Power OFF ISP after probe
- Set the device to suspended state with pm_runtime_set_suspended()
- Enable runtime PM only after the device is fully initialized

When reading from the I2DR register, right after releasing the bus by
clearing MSTA and MTX, the I2C controller might still generate an
additional clock cycle which can cause devices to misbehave. Ensure to
only read from I2DR after the bus is not busy anymore. Because this
requires polling, the read of the last byte is moved outside of the
interrupt handler.
An example for such a failing transfer is this:
i2ctransfer -y -a 0 w1@0x00 0x02 r1
Error: Sending messages failed: Connection timed out
It does not happen with every device because not all devices react to
the additional clock cycle.

The driver was disabling the USB2 PHY clock immediately after register
initialization in probe() and after each reset operation. This left the
PHY unclocked even though it must remain active for USB functionality.
The behavior appeared to work only when another driver
(e.g., USB controller) had already enabled the clock, making operation
unreliable and hardware-dependent. In configurations where this driver
is the sole clock user, USB functionality would fail.
Fix this by:
- Enabling the clock once in probe() via pm_runtime_resume_and_get()
- Removing all pm_runtime_put() calls from assert/deassert/status
- Registering a devm cleanup action to release the clock at removal
- Removed rzv2h_usbphy_assert_helper() and its call in
rzv2h_usb2phy_reset_probe()
This ensures the PHY clock remains enabled for the entire device lifetime,
preventing instability and aligning with hardware requirements.

Up until now there was only one auxiliary device that bnxt
created and that was for RoCE driver. bnxt fwctl is also
going to use an aux bus device that bnxt should create.
This requires some nomenclature changes and refactoring of
the existing bnxt aux dev functions.
Convert 'aux_priv' and 'edev' members of struct bnxt into
arrays where each element contains supported auxbus device's
data. Move struct bnxt_aux_priv from bnxt.h to ulp.h because
that is where it belongs. Make aux bus init/uninit/add/del
functions more generic which will loop through all the aux
device types. Make bnxt_ulp_start/stop functions (the only
other common functions applicable to any aux device) loop
through the aux devices to update their config and states.
Make callers of bnxt_ulp_start() call it only when there
are no errors.
Also, as an improvement in code, bnxt_register_dev() can skip
unnecessary dereferencing of edev from bp, instead use the
edev pointer from the function parameter.
Future patches will reuse these functions to add an aux bus
device for fwctl.

Additionally, remove the skb_mark_for_recycle() call since the skb is
backed by the NAPI page frag allocator, not page_pool. Marking a
non-page_pool skb for recycle causes the free path to return pages to
a page_pool that does not own them, corrupting page_pool state.
The non-ZC path (emac_rx_packet) does not have these issues because it

Commit 7d6899fb69 ("ovl: fsync after metadata copy-up") was done to
fix durability of overlayfs copy up on an upper filesystem which does
not enforce ordering on storing of metadata changes (e.g. ubifs).
In an earlier revision of the regressing commit by Lei Lv, the metadata
fsync behavior was opt-in via a new "fsync=strict" mount option.
We were hoping that the opt-in mount option could be avoided, so the
change was only made to depend on metacopy=off, in the hope of not
hurting performance of metadata heavy workloads, which are more likely
to be using metacopy=on.
This hope was proven wrong by a performance regression report from Google
COS workload after upgrade to kernel 6.12.
This is an adaptation of Lei's original "fsync=strict" mount option
to the existing upstream code.
The new mount option is mutually exclusive with the "volatile" mount
option, so the latter is now an alias to the "fsync=volatile" mount
option.

This adds fixes and improvements for already supported devices.
In particular:
- The gpio-ranges pin could was fixed in MT6795, MT7981B, and
MT7986A SoCs, as the very last GPIO was unusable; Even though
anyway unused, this fixes the hardware description.
- Model string fixes for Bananapi BPI-R4 Pro 4E/8X: now the
correct model is shown.
- The MT6359 PMIC gets disambiguation for two default regulator
names, mainly fixing issues seen on U-Boot, but also making
the regulators visually distinguishable in a summary...!
- Aliases for eMMC/SD controllers added in MT8365 EVK board,
MT8395 Radxa NIO-12L and Genio 1200 for consistency
- Fixes to the MediaTek AUDSYS devicetree binding
....and honorable mention goes to:
- MT8195 Cherry Chromebooks get their WiFi on PCI Express and
Bluetooth on USB described with the proper power supplies now
tied to the correct devices (USB VBUS and PCIE3v3): this is
now described almost perfectly, or at least links the right
resources in the right places.
This is also done as a preparation for when the M.2 E-Key
connector binding will be upstreamed.
- MT8195 Cherry Dojo gets its M.2 M-Key slot correctly described
with the new pcie-m2-m-connector binding.

Due to Rust macro scoping rules, all macros defined in a crate using
`#[macro_export]` end up in the top-level. For the list macros, we
re-export them inside the list module, and expect users to use
`kernel::list::macro_name!()`.
Use `#[doc(hidden)]` on the macro definition, and use `#[doc(inline)]` on
the re-export to make the macro appear to be defined at module-level inside
documentation.
The other exported types are already automatically `#[doc(inline)]` because
they are defined in a non-public module, so there is no need to split the
macro re-exports out.

We're mixing up the GT FIFO debug checks (overflows and such)
with RMbus unclaimed register checks. The two are quite different
things as RMbus is only relevant for display registers, and the
GT FIFO only relevant for GT registers.
Split the GT FIFO debugs out from the unclaimed register logic
and just do the checks during forcewake_get() and early init.
That is still sufficient to detect if any errors have happened.
Any errors would anyway be caused by overflowing the FIFO
rather than accessing specific registers, so trying to figure
out exactly when the error happened isn't particularly useful.
To fix such issues we'd rather have to do something to slow down
the rate at which registers are accessed (eg. increase
GT_FIFO_NUM_RESERVED_ENTRIES or something).

The live_forcewake_domains selftest doesn't really test anything
particularly sensible. It only runs on platforms that have RMbus
unclaimer error detection, but that only catches display registers
which the test doesn't even access.
I suppose if we really wanted to we might try to make the test
exercise the GT FIFO instead by writing GT registers as fast
as possible, and then checking GTFIFODBG to see if the FIFO has
overflowed. But dunno if there's much point in that. I think a
GT FIFO overflow might even be fatal to the machine.
So in its current for the test doesn't really make sense,
and it's in the way of moving all the RMbus noclaim stuff
to the display driver side. So let's just get rid of it.
