The debugfs read callback must advance ppos or users using read() on
the file descriptor will never get the EOL. This wasn't spotted before
as I was using busybox cat for testing which uses sendfile() internally
and only noticed it now when switched to cat from coreutils.

We only hit unregister_allocated_timer() if the argument to
aspeed_gpio_set_config() is 0, but we can't be calling through
gpiod_set_debounce() from gpio_keys_probe() unless the gpio-keys button has a
non-zero debounce interval.
Commit 6581eaf0e890 ("gpio: use new gpio_set_config() helper in more places")
spreads the use of gpio_set_config() to the debounce and transitory
state configuration paths. The implementation of gpio_set_config() is:
> static int gpio_set_config(struct gpio_chip *gc, unsigned offset,
> enum pin_config_param mode)
> {
> unsigned long config = { PIN_CONF_PACKED(mode, 0) };
>
> return gc->set_config ? gc->set_config(gc, offset, config) : -ENOTSUPP;
> }
Here it packs its own config value with a fixed argument of 0; this is
incorrect behaviour for implementing the debounce and transitory functions, and
the debounce and transitory gpio_set_config() call-sites now have an undetected
type mismatch as they both already pack their own config parameter (i.e. what
gets passed is not an `enum pin_config_param`). Indeed this can be seen in the
small diff for 6581eaf0e890:

In cpu_to_drc_index() in the case when FW_FEATURE_DRC_INFO is absent,
we currently use of_read_property() to obtain the pointer to the array
corresponding to the property "ibm,drc-indexes". The elements of this
array are of type __be32, but are accessed without any conversion to
the OS-endianness, which is buggy on a Little Endian OS.
Fix this by using of_property_read_u32_index() accessor function to
safely read the elements of the array.

Renaming a netdev-trigger-tracked interface was resulting in an
unbalanced dev_hold().
Example:
> iw phy phy0 interface add foo type __ap
> echo netdev > trigger
> echo foo > device_name
> ip link set foo name bar
> iw dev bar del
[ 237.355366] unregister_netdevice: waiting for bar to become free. Usage count = 1
[ 247.435362] unregister_netdevice: waiting for bar to become free. Usage count = 1
[ 257.545366] unregister_netdevice: waiting for bar to become free. Usage count = 1
Above problem was caused by trigger checking a dev->name which obviously
changes after renaming an interface. It meant missing all further events
including the NETDEV_UNREGISTER which is required for calling dev_put().
This change fixes that by:
1) Comparing device struct *address* for notification-filtering purposes
2) Dropping unneeded NETDEV_CHANGENAME code (no behavior change)

With ti-sysc interconnect target module, we can allocate struct omap_hwmod
data based on the devicetree data. This allows dropping the static SoC
specific data eventually so we will only boot with data we actually need.
To allocate struct omap_hwmod dynamically, we need to add a mutex for
modifying the list, and remove __init for few functions.
Note that we are not initialized oh->_clk or the optional clocks and their
related quirks. That can be directly handled by the interconnect target
module driver.

For dynamically allocated struct hwmod entries probing with ti-sysc
interconnect target module driver, we need to specify the initial default
state the same way as we do for the platform data cases.
Let's prepare for that by adding _HWMOD_STATE_DEFAULT that we can then
use to set the initial default state without a need to add similar
CONFIG_PM handling in multiple places.

For dynamically allocated sysconfig data we only need to allocate a new
class for the cases where the class is shared. For dynamically allocated
struct omap_hwmod we will always allocate a new class.
Let's add detection for when we need to allocate a new class by comparing
the class name against the module name. If they match, there's no need
to allocate a new calls as we don't have case of mixed platform data and
dts data initialized modules for the same class.
Let's also move the init of class data inside the spinlock.

Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.
We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

Previously the green and amber LEDs on this quad PHY were solid, to
indicate an encoding of the link speed (10/100/1000).
This keeps the LEDs always on just as before, but now they flash on
Rx/Tx activity.

When running a syz script, a panic occurred:
[ 156.088228] BUG: KASAN: use-after-free in tipc_disc_timeout+0x9c9/0xb20 [tipc]
[ 156.094315] Call Trace:
[ 156.094844] <IRQ>
[ 156.095306] dump_stack+0x7c/0xc0
[ 156.097346] print_address_description+0x65/0x22e

[ 156.112749] run_timer_softirq+0xb51/0x1090
It was caused by the netns freed without deleting the discoverer timer,
while later on the netns would be accessed in the timer handler.
The timer should have been deleted by tipc_net_stop() when cleaning up a
netns. However, tipc has been able to enable a bearer and start d->timer
without the local node_addr set since Commit 52dfae5c85a4 ("tipc: obtain
node identity from interface by default"), which caused the timer not to
be deleted in tipc_net_stop() then.
So fix it in tipc_net_stop() by changing to check local node_id instead
of local node_addr, as Jon suggested.
While at it, remove the calling of tipc_nametbl_withdraw() there, since
tipc_nametbl_stop() will take of the nametbl's freeing after.
Fixes: 52dfae5c85a4 ("tipc: obtain node identity from interface by default")

This patch implements accessors for the QCA8337 MDIO access
through the MDIO_MASTER register, which makes it possible to
access the PHYs on slave-bus through the switch. In cases
where the switch ports are already mapped via external
"phy-phandles", the internal mdio-bus is disabled in order to
prevent a duplicated discovery and enumeration of the same
PHYs. Don't use mixed external and internal mdio-bus
configurations, as this is not supported by the hardware.

This belated patch implements Andrew Lunn's request of
"remove the phy_read() and phy_write() functions."
<https://lore.kernel.org/patchwork/comment/902734/>
While seemingly harmless, this causes the switch's user
port PHYs to get registered twice. This is because the
DSA subsystem will create a slave mdio-bus not knowing
that the qca8k_phy_(read|write) accessors operate on
the external mdio-bus. So the same "bus" gets effectively
duplicated.

In the example, the phy at phy@0 is clashing with
the switch0@0 at the same address. Usually, the switches
are accessible through pseudo PHYs which in case of the
qca8k are located at 0x10 - 0x18.

XFS applies more strict serialization constraints to unaligned
direct writes to accommodate things like direct I/O layer zeroing,
unwritten extent conversion, etc. Unaligned submissions acquire the
exclusive iolock and wait for in-flight dio to complete to ensure
multiple submissions do not race on the same block and cause data
corruption.
This generally works in the case of an aligned dio followed by an
unaligned dio, but the serialization is lost if I/Os occur in the
opposite order. If an unaligned write is submitted first and
immediately followed by an overlapping, aligned write, the latter
submits without the typical unaligned serialization barriers because
there is no indication of an unaligned dio still in-flight. This can
lead to unpredictable results.
To provide proper unaligned dio serialization, require that such
direct writes are always the only dio allowed in-flight at one time
for a particular inode. We already acquire the exclusive iolock and
drain pending dio before submitting the unaligned dio. Wait once
more after the dio submission to hold the iolock across the I/O and
prevent further submissions until the unaligned I/O completes. This
is heavy handed, but consistent with the current pre-submission
serialization for unaligned direct writes.

Commit 656fe2ba85e8 (tracing: Use hist trigger's var_ref array to
destroy var_refs) centralized the destruction of all the var_refs
in one place so that other code didn't have to do it.
The track_data_destroy() added later ignored that and also destroyed
the track_data var_ref, causing a double-free error flagged by KASAN.
