max_zone_append_sectors differs from all other queue limits in that the
final value used is not stored in the queue_limits but needs to be
obtained using queue_limits_max_zone_append_sectors helper. This not
only adds (tiny) extra overhead to the I/O path, but also can be easily
forgotten in file system code.
Add a new max_hw_zone_append_sectors value to queue_limits which is
set by the driver, and calculate max_zone_append_sectors from that and
the other inputs in blk_validate_zoned_limits, similar to how
max_sectors is calculated to fix this.

The commit 4c39529663b9 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-cache
code.
The dm-cache code allocates a slab cache for each device. This commit
changes it to allocate just one slab cache in the module init function.

The commit 4c39529663b9 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-bufio
code. The dm-bufio code allocates a slab cache with each client. It is
not possible to preallocate the caches in the module init function
because the size of auxiliary per-buffer data is not known at this point.
So, this commit changes dm-bufio so that it appends a unique atomic value
to the cache name, to avoid the warnings.

For the case of an in the write path, we need to undo the increment in

In ublk_ch_mmap(), queue id is calculated in the following way:
(vma->vm_pgoff << PAGE_SHIFT) / `max_cmd_buf_size`
'max_cmd_buf_size' is equal to
`UBLK_MAX_QUEUE_DEPTH * sizeof(struct ublksrv_io_desc)`
and UBLK_MAX_QUEUE_DEPTH is 4096 and part of UAPI, so 'max_cmd_buf_size'
is always page aligned in 4K page size kernel. However, it isn't true in
64K page size kernel.
Fixes the issue by always rounding up 'max_cmd_buf_size' with PAGE_SIZE.

Notice that hybrid_init_cpu_capacity_scaling() only needs to hold
hybrid_capacity_lock around __hybrid_init_cpu_capacity_scaling()
calls, so introduce a "locked" wrapper around the latter and call
it from the former. This allows to drop a local variable and a
label that are not needed any more.
Also, rename __hybrid_init_cpu_capacity_scaling() to
__hybrid_refresh_cpu_capacity_scaling() for consistency.
Interestingly enough, this fixes a locking issue introduced by commit
929ebc93ccaa ("cpufreq: intel_pstate: Set asymmetric CPU capacity on
hybrid systems") that put an arch_enable_hybrid_capacity_scale() call
under hybrid_capacity_lock, which was a mistake because the latter is
acquired in CPU hotplug paths and so it cannot be held around
cpus_read_lock() calls.

brcmf_sdiod_sglist_rw()
This patch fixes a NULL pointer dereference bug in brcmfmac that occurs
when a high 'sd_sgentry_align' value applies (e.g. 512) and a lot of queued SKBs
are sent from the pkt queue.
The problem is the number of entries in the pre-allocated sgtable, it is
nents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1.
Given the default [rt]xglom_size=32 it's actually 35 which is too small.
Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKB
is added for each original SKB if tailroom isn't enough to hold tail_pad.
At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop"
in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next return
NULL and this causes the oops.
The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handle
the worst-case.
Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464
additional bytes of memory.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/net/wireless to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.
En passant several whitespace changes are done to make indentation
consistent in the struct initializers.

The fixed patch introduced an additional condition to enter the scope
where the 'root' device_node is released (!settings->board_type,
currently 'err'), which avoid decrementing the refcount with a call to
of_node_put() if that second condition is not satisfied.
Move the call to of_node_put() to the point where 'root' is no longer
required to avoid leaking the resource if err is not zero.

Add support for LTC7841. The LTC7841 is a high performance
PolyPhase® single output synchronous boost converter controller.
Multiphase operation reduces input and output capacitor
requirements and allows the use of smaller inductors than the
single-phase equivalent.
The relevant registers in the LTC7841 are similar to the
LTC7880, only reduced by some amount. So it's just a matter of adding
the chip id. The device also doesn't support polling, on top of the
reduced register set, so a separate case for setting the chip info is
added.

Add support for manipulating the internal heater of sht4x devices.
Enabling the heater removes condensed water from the sensor surface
which disturbs the relative humidity measurements.
The heater can operate at three heating levels (20, 110 or 200
milliwatts). Also, two heating durations may be selected (0.1 or 1s).
Once the heating time elapses the heater is automatically switched off.

* struct sht4x_data: add heating_complete timestamp
* struct sht4x_data: add data_pending flag
* heater_enable_store: return -EINVAL if input != 1
* heater_enable_store: check for data->heating_complete and update it
* heater_enable_store: set data_pending flag after heating request
* sht4x_read_values: msleep if heating in progress
* sht4x_read_values: dont send measurement request if data_pending
* heater_enable attr: make it RW
* Documentation: update info about heater_enable attr
Changes since v2:
* heater_enable_store: remove unnecessary if
* Documentation: remove incorrect info about turning off the heater
* be more specific in the patch description

* explain the use case of the new attributes set
* heater_enable attr: make it write-only
* heater_enable_store: define cmd as u8 instead of u8*
* heater_enable_store: remove unreachable data path

Several drivers return the same static value in their is_visible
callback, what results in code duplication. Therefore add an option
for drivers to specify a static visibility directly.

Theobroma Systems Mule is an MCU that emulates a set of I2C devices,
among which is an amc6821 and other devices that are reachable through
an I2C-mux.
The devices on the mux can be selected by writing the appropriate device
number to an I2C config register (amc6821: reg 0xff)
Implement "tsd,mule" compatible to instantiate the I2C-mux platform device
when probing the amc6821.

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.
