Specify USBH_PEN GPIO being active-low rather than active-high.
Note that this should not have any functional impact as for fixed
regulators the regular GPIO polarity is ignored and a true active-high
enable GPIO would need an additional enable-active-high property which
is/was not the case here. However, this may be rather confusing which
this patch fixes.

The current reference management logic of io scheduler modules contains
refcnt problems. For example, blk_mq_init_sched may fail before or after
the calling of e->ops.init_sched. If it fails before the calling, it does
nothing to the reference to the io scheduler module. But if it fails after
the calling, it releases the reference by calling kobject_put(&eq->kobj).
As the callers of blk_mq_init_sched can't know exactly where the failure
happens, they can't handle the reference to the io scheduler module
properly: releasing the reference on failure results in double-release if
blk_mq_init_sched has released it, and not releasing the reference results
in ghost reference if blk_mq_init_sched did not release it either.
The same problem also exists in io schedulers' init_sched implementations.
We can address the problem by adding releasing statements to the error
handling procedures of blk_mq_init_sched and init_sched implementations.
But that is counterintuitive and requires modifications to existing io
schedulers.
Instead, We make elevator_alloc get the io scheduler module references
that will be released by elevator_release. And then, we match each
elevator_get with an elevator_put. Therefore, each reference to an io
scheduler module explicitly has its own getter and releaser, and we no
longer need to worry about the refcnt problems.
The bugs and the patch can be validated with tools here:

Commit b5dc5d4d1f ("block,bfq: Disable writeback throttling") tries to
disable wbt for bfq, it's done by calling wbt_disable_default() in
bfq_init_queue(). However, wbt is still enabled if default elevator is
bfq:
device_add_disk
elevator_init_mq
bfq_init_queue
wbt_disable_default -> done nothing
blk_register_queue
wbt_enable_default -> wbt is enabled
Fix the problem by adding a new flag ELEVATOR_FLAG_DISBALE_WBT, bfq
will set the flag in bfq_init_queue, and following wbt_enable_default()
won't enable wbt while the flag is set.

This won't cause any severe problem currently, however, this doesn't
seems appropriate:
1) 'ioc->params' is read from multiple places without holding
'ioc->lock', unexpected value might be read if writing it concurrently.
2) If configuration is changed while io is throttling, the functionality
might be affected. For example, if module params is updated and cost
becomes smaller, waiting for timer that is caculated under old
configuration is not appropriate.

2) update params to local variable without lock;
3) hold lock to write local variable to 'ioc->params';
In theroy, if user updates params concurrenty, the params might be lost:
t1: update params a t2: update params b

memcpy(qos, ioc->params.qos, sizeof(qos))

The quad8_action_read() function checks the Count function mode and
Count direction without first acquiring a lock. This is a race condition
because the function mode could change by the time the direction is
checked.
Because the quad8_function_read() already acquires a lock internally,
the quad8_function_read() is refactored to spin out the no-lock code to
a new quad8_function_get() function.
To resolve the race condition in quad8_action_read(), a lock is acquired
before calling quad8_function_get() and quad8_direction_read() in order
to get both function mode and direction atomically.

fill_note_info() iterates through the list of threads collected in
mm->core_state->dumper, allocating a struct elf_thread_core_info
instance for each and linking those into a list.
We need the entry corresponding to current to be first in the
resulting list, so the logics for list insertion is
if it's for current or list is empty
insert in the head
else
insert after the first element
However, in mm->core_state->dumper the entry for current is guaranteed
to be the first one. Which means that both parts of condition will
be true on the first iteration and neither will be true on all subsequent
ones.
Taking the first iteration out of the loop simplifies things nicely...

Pull io_uring follow-up from Jens Axboe:
"Currently the zero-copy has automatic fallback to normal transmit, and
it was decided that it'd be cleaner to return an error instead if the
socket type doesn't support it.
Zero-copy does work with UDP and TCP, it's more of a future proofing
kind of thing (eg for samba)"
* tag 'io_uring-6.1-2022-10-22' of git://git.kernel.dk/linux:
io_uring/net: fail zc sendmsg when unsupported by socket
io_uring/net: fail zc send when unsupported by socket
net: flag sockets supporting msghdr originated zerocopy
Usual bunch of driver fixes + one set of fixes for driver bugs
introduced by a core change to how buffer attributes are handled.
- buffer attributes
* Remove usage of IIO_CONST_ATTR() for buffer attributes in all drivers
where this occurred as that broke wrapping code need to duplicate these
for multiple buffer support. The minimal fix is moving to
IIO_DEVICE_ATTR_RO() with separate _show() routines. A cleanup of
this code, preventing similar issues in future will follow next merge
window.
- tools/iio
* Wrong handling of number of digits in the number 0.
- adi,ltc2983
* Avoid reallocating channels on each wake up from sleep by moving
that step out of the ltc2983_setup() function.
- microchip,mcp3911
* Wrong ID bits + masking in debug prints.
* Fix ARRAY_SIZE() vs sizeof() mix up.
* Handle NULL return on trigger allocation failure correctly.
- st,stm32-adc:
* Ensure we initialize sampling time even when optional property not
provided in DT. Internal channels require a minimum value that will
not otherwise be set.
- taos,tsl2583
* Fix a double call of iio_device_unregister() via device managed and
un-managed paths.
