Drop the wake-irq enable and disable helpers which have not been used
since commit bed570307ed7 ("PM / wakeirq: Fix dedicated wakeirq for
drivers not using autosuspend").
Note that these functions are essentially just leftovers from the first
iteration of the wake-irq implementation where device drivers were
supposed to call these functions themselves instead of PM core (as
is also indicated by the bogus kernel doc comments).

The decision whether to enable a wake irq during suspend can not be done
based on the runtime PM state directly as a driver may use wake irqs
without implementing runtime PM. Such drivers specifically leave the
state set to the default 'suspended' and the wake irq is thus never
enabled at suspend.
Add a new wake irq flag to track whether a dedicated wake irq has been
enabled at runtime suspend and therefore must not be enabled at system
suspend.
Note that pm_runtime_enabled() can not be used as runtime PM is always
disabled during late suspend.

Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal
zone parameters structure"), thermal_zone_device_register() allocates
a copy of the tzp argument and frees it when unregistering, so
thermal_of_zone_register() now ends up leaking its original tzp and
double-freeing the tzp copy. Fix this by locating tzp on stack instead.

Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal zone
parameters structure"), thermal_zone_device_register() allocates a copy
of the tzp argument and callers need not explicitly manage its lifetime.
This means the function no longer cares about the parameter being
mutable, so constify it.
No functional change.

After syncing the enable status of VCN33_WIFI to VCN33_BT, the driver
will disable VCN33_WIFI. If it fails it will error out with a message.
However the error message incorrectly refers to VCN33_BT.
Fix the error message so that it correctly refers to VCN33_WIFI.

Clear MV_V2_PORT_CTRL_PWRDOWN bit to set power up for 88x3310 PHY,
it sometimes does not take effect immediately. And a read of this
register causes the bit not to clear. This will cause mv3310_reset()
to time out, which will fail the config initialization. So add a delay
before the next access.

Pull regmap fixes from Mark Brown:
"Three fixes here:
- The issues with accounting for register and padding length on raw
buses turn out to be quite widespread in custom buses.
In order to avoid disturbing anything drop the initial fixes and
fall back to a point fix in the SMBus code where the issue was
originally noticed, a more substantial refactoring of the API which
ensures that all buses make the same assumptions will follow.
- The generic regcache code had been forcing on async I/O which did
not work with the new maple tree sync code when used with SPI.
Since that was mainly for the rbtree cache and the assumptions
about hardware that drove the choice are probably not true any more
fix this by pushing the enablement of async down into the rbtree
code.
This probably also makes cache syncs for systems faster though it's
not the point.
- The test code was triggering use of the rbtree and maple tree
caches with dynamic allocation of nodes since all the testing is
with RAM backed caches with no I/O performance issues.
Just disable the locking in the tests to avoid triggering warnings
when allocation debugging is turned on, it's not really what's
being tested"

Problem:
The max_loop parameter is used for 2 different purposes:
1) initial number of loop devices to pre-create on init
2) maximum number of loop devices to add on access/open()
Historically, its default value (zero) caused 1) to create non-zero
number of devices (CONFIG_BLK_DEV_LOOP_MIN_COUNT), and no hard limit on
2) to add devices with autoloading.
However, the default value changed in commit 85c50197716c ("loop: Fix
the max_loop commandline argument treatment when it is set to 0") to
CONFIG_BLK_DEV_LOOP_MIN_COUNT, for max_loop=0 not to pre-create devices.
That does improve 1), but unfortunately it breaks 2), as the default
behavior changed from no-limit to hard-limit.
Example:
For example, this userspace code broke for N >= CONFIG, if the user
relied on the default value 0 for max_loop:
mknod("/dev/loopN");
open("/dev/loopN"); // now fails with ENXIO
Though affected users may "fix" it with (loop.)max_loop=0, this means to
require a kernel parameter change on stable kernel update (that commit
Fixes: an old commit in stable).
Solution:
The original semantics for the default value in 2) can be applied if the
parameter is not set (ie, default behavior).
This still keeps the intended function in 1) and 2) if set, and that
commit's intended improvement in 1) if max_loop=0.
Before 85c50197716c:
- default: 1) CONFIG devices 2) no limit
- max_loop=0: 1) CONFIG devices 2) no limit
- max_loop=X: 1) X devices 2) X limit
After 85c50197716c:
- default: 1) CONFIG devices 2) CONFIG limit (*)
- max_loop=0: 1) 0 devices (*) 2) no limit
- max_loop=X: 1) X devices 2) X limit
This commit:
- default: 1) CONFIG devices 2) no limit (*)
- max_loop=0: 1) 0 devices 2) no limit
- max_loop=X: 1) X devices 2) X limit
Future:
The issue/regression from that commit only affects code under the
CONFIG_BLOCK_LEGACY_AUTOLOAD deprecation guard, thus the fix too is
contained under it.
Once that deprecated functionality/code is removed, the purpose 2) of
max_loop (hard limit) is no longer in use, so the module parameter
description can be changed then.

This requires a bit of background. Properly done a modeset driver's
unload/remove sequence should be
drm_dev_unplug();
drm_atomic_helper_shutdown();
drm_dev_put();
The trouble is that the drm_dev_unplugged() checks are by design racy,
they do not synchronize against all outstanding ioctl. This is because
those ioctl could block forever (both for modeset and for driver
specific ioctls), leading to deadlocks in hotunplug. Instead the code
sections that touch the hardware need to be annotated with
drm_dev_enter/exit, to avoid accessing hardware resources after the
unload/remove has finished.
To avoid use-after-free issues all the involved userspace visible
objects are supposed to hold a reference on the underlying drm_device,
like drm_file does.
The issue now is that we missed one, the atomic modeset ioctl can be run
in a nonblocking fashion, and in that case it cannot rely on the implied
drm_device reference provided by the ioctl calling context. This can
result in a use-after-free if an nonblocking atomic commit is carefully
raced against a driver unload.
Fix this by unconditionally grabbing a drm_device reference for any
drm_atomic_state structures. Strictly speaking this isn't required for
blocking commits and TEST_ONLY calls, but it's the simpler approach.
Thanks to shanzhulig for the initial idea of grabbing an unconditional
reference, I just added comments, a condensed commit message and fixed a
minor potential issue in where exactly we drop the final reference.

In iavf_adminq_task(), if the function can't acquire the
adapter->crit_lock, it checks if the driver is removing. If so, it simply
exits without re-enabling the interrupt. This is done to ensure that the
task stops processing as soon as possible once the driver is being removed.
However, if the IAVF_FLAG_PF_COMMS_FAILED is set, the function checks this
before attempting to acquire the lock. In this case, the function exits
early and re-enables the interrupt. This will happen even if the driver is
already removing.
Avoid this, by moving the check to after the adapter->crit_lock is
acquired. This way, if the driver is removing, we will not re-enable the
interrupt.

In iavf_adminq_task(), if kzalloc() fails to allocate the event.msg_buf,
the function will exit without releasing the adapter->crit_lock.
This is unlikely, but if it happens, the next access to that mutex will
deadlock.
Fix this by moving the unlock to the end of the function, and adding a new
label to allow jumping to the unlock portion of the function exit flow.

mdio_bus_init() and phy_driver_register() both have error paths, and if
those are ever hit, ethtool will have a stale pointer to the
phy_ethtool_phy_ops stub structure, which references memory from a
module that failed to load (phylib).
It is probably hard to force an error in this code path even manually,
but the error teardown path of phy_init() should be the same as
phy_exit(), which is now simply not the case.

Commit c13380a55522 ("Bluetooth: btusb: Do not require hardcoded
interface numbers") inadvertedly broke bluetooth on Intel Macbook 2014.
The intention was to keep behavior intact when BTUSB_IFNUM_2 is set and
otherwise allow any interface numbers. The problem is that the new logic
condition omits the case where bInterfaceNumber is 0.
Fix BTUSB_IFNUM_2 handling by allowing both interface number 0 and 2
when the flag is set.

83efeeeb3d04 ("tty: Allow TIOCSTI to be disabled") broke BRLTTY's
ability to simulate keypresses on the console, thus effectively breaking
braille keyboards of blind users.
This restores the TIOCSTI feature for CAP_SYS_ADMIN processes, which
BRLTTY is, thus fixing braille keyboards without re-opening the security

The length information for available buffer space for CCA
replies is covered with two fields in the T6 header prepended
on each CCA reply: fromcardlen1 and fromcardlen2. The sum of
these both values must not exceed the AP bus limit for this
card (24KB for CEX8, 12KB CEX7 and older) minus the always
present headers.
The current code adjusted the fromcardlen2 value in case
of exceeding the AP bus limit when there was a non-zero
value given from userspace. Some tests now showed that this
was the wrong assumption. Instead the userspace value given for
this field should always be trusted and if the sum of the
two fields exceeds the AP bus limit for this card the first
field fromcardlen1 should be adjusted instead.
So now the calculation is done with this new insight in mind.
Also some additional checks for overflow have been introduced
and some comments to provide some documentation for future
maintainers of this complicated calculation code.
Furthermore the 128 bytes of fix overhead which is used
in the current code is not correct. Investigations showed
that for a reply always the same two header structs are
prepended before a possible payload. So this is also fixed
with this patch.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
