The DSDTs of CHT devices using the Dollar Cove TI PMIC, all use
LDO1 - LDO14 names for the DSDT power opregion field names.
Add comments with these fields to make it easier to see which PMIC
registers are being set by ACPI code using these.
Note that LDO4 is missing and the mapped registers jump from 0x43
to 0x45 to match. This matches with how the fields are declared
in the DSDT where LDO4 is skipped too. Note there is no hole in
the field addresses, LDO4 is simply just not defined on either side.

On the Dell Inspiron 3505, the battery model name
is represented as a hex string containing seven numbers,
causing it to be larger than the current maximum string
length (32).
Increase this length to 64 to avoid truncating the string
in such cases. Also introduce a common define for the length.

If a buffer containing ASCII characters is not NUL-terminated
(which is perfectly legal according to the ACPI specification),
the ACPI battery driver might not honor its length.
Fix this by limiting the amount of data to be copied to
the buffer length while also using strscpy() to make sure
that the resulting string is always NUL-terminated.
Also replace strncpy() vs strscpy().

Every power mode of static power slider has its own AC and DC power
settings.
When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.
Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.

thermal driver (Rafael Wysocki).

unprivileged ublk device is helpful for container use case, such
as: ublk device created in one unprivileged container can be controlled
and accessed by this container only.
Implement this feature by adding flag of UBLK_F_UNPRIVILEGED_DEV, and if
this flag isn't set, any control command has been run from privileged
user. Otherwise, any control command can be sent from any unprivileged
user, but the user has to be permitted to access the ublk char device
to be controlled.
In case of UBLK_F_UNPRIVILEGED_DEV:
1) for command UBLK_CMD_ADD_DEV, it is always allowed, and user needs
to provide owner's uid/gid in this command, so that udev can set correct
ownership for the created ublk device, since the device owner uid/gid
can be queried via command of UBLK_CMD_GET_DEV_INFO.
2) for other control commands, they can only be run successfully if the
current user is allowed to access the specified ublk char device, for
running the permission check, path of the ublk char device has to be
provided by these commands.
Also add one control of command UBLK_CMD_GET_DEV_INFO2 which always
include the char dev path in payload since userspace may not have
knowledge if this device is created in unprivileged mode.
For applying this mechanism, system administrator needs to take
the following policies:
1) chmod 0666 /dev/ublk-control
2) change ownership of ublkcN & ublkbN
- chown owner_uid:owner_gid /dev/ublkcN
- chown owner_uid:owner_gid /dev/ublkbN
Both can be done via one simple udev rule.
Userspace:
https://github.com/ming1/ubdsrv/tree/unprivileged-ublk
'ublk add -t $TYPE --un_privileged=1' is for creating one un-privileged
ublk device if the user is un-privileged.

Userspace side only knows device ID, but the associated path of ublkc* and
ublkb* could be changed by udev, and that depends on userspace's policy, so
add parameter of UBLK_PARAM_TYPE_DEVT for retrieving major/minor of the
ublkc* and ublkb*, then user may figure out major/minor of the ublk disks
he/she owns. With major/minor, it is easy to find the device node path.

This require_context attribute originated in a proposed sparse patch by
Philipp Reisner back in 2008. Johannes Berg had a different solution to
a similar problem, and that patch "won" in the end; so the require_context
thing never got merged. The whole history can be read at [0].
DRBD kept using these annotations anyway for a while. Nowadays, on a
modern unmodified sparse, they obviously do nothing, and they are hardly
used anymore anyway.
So, just remove the definitions of these macros.

in_dev_get() can return NULL which will cause a failure once idev is
dereferenced in in_dev_for_each_ifa_rtnl(). This patch adds a
check for NULL value in idev beforehand.

Commit 6e9f05dc66f9 ("libnvdimm/pfn_dev: increase MAX_STRUCT_PAGE_SIZE")
...updated MAX_STRUCT_PAGE_SIZE to account for sizeof(struct page)
potentially doubling in the case of CONFIG_KMSAN=y. Unfortunately this
doubles the amount of capacity stolen from user addressable capacity for
everyone, regardless of whether they are using the debug option. Revert
that change, mandate that MAX_STRUCT_PAGE_SIZE never exceed 64, but
allow for debug scenarios to proceed with creating debug sized page maps
with a compile option to support debug scenarios.
Note that this only applies to cases where the page map is permanent,
i.e. stored in a reservation of the pmem itself ("--map=dev" in "ndctl
create-namespace" terms). For the "--map=mem" case, since the allocation
is ephemeral for the lifespan of the namespace, there are no explicit
restriction. However, the implicit restriction, of having enough
available "System RAM" to store the page map for the typically large
pmem, still applies.

Dan Carpenter points out that the return code was not set in commit
60c8b4aebd8e ("nvmem: core: fix cleanup after dev_set_name()"), but
this is not the only issue - we also need to zero wp_gpio to prevent
gpiod_put() being called on an error value.

nvmem_add_cells() could return an error after some cells are already
added to the provider. In this case, the added cells are not removed.

In of_nvmem_cell_get(), of_get_next_parent() is used on cell_np. This
will decrement the refcount on cell_np, but cell_np is still used later
in the code. Use of_get_parent() instead and of_node_put() in the
appropriate places.

The i.MX6 CPU frequency driver sometimes fails to register at boot time
due to nvmem_cell_read_u32() sporadically returning -ENOENT.
This happens because there is a window where __nvmem_device_get() in
of_nvmem_cell_get() is able to return the nvmem device, but as cells
have been setup, nvmem_find_cell_entry_by_node() returns NULL.
The occurs because the nvmem core registration code violates one of the
fundamental principles of kernel programming: do not publish data
structures before their setup is complete.
Fix this by making nvmem core code conform with this principle.

If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not
put this. While a minimal fix for this would be to add the gpiod_put()
call, we can do better if we split device_register(), and use the
tested nvmem_release() cleanup code by initialising the device early,
and putting the device.
This results in a slightly larger fix, but results in clear code.
Note: this patch depends on "nvmem: core: initialise nvmem->id early"
and "nvmem: core: remove nvmem_config wp_gpio".
