When building with a version of GCC prior to 8.x, there is an error

Clang versions prior to 17.x show a similar error:

.vbus_desc = bq24190_vbus_desc,
^~~~~~~~~~~~~~~~~
1 error generated.
Newer compilers have decided to accept these structures as compile time
constants as an extension. To resolve this issue for all supported
compilers, change the vbus_desc member in 'struct bq24190_chip_info' to
a pointer, as it is only ever passed by reference anyways, and adjust
the assignments accordingly.

Currently, a not-yet-entirely-initialized battmgr (e.g. with pd-mapper
not having yet started or ADSP not being up etc.) results in a couple of
zombie power supply devices hanging around.
This is particularly noticeable when trying to suspend the device (even
s2idle): the PSY-internal thermal zone is inaccessible and returns
-ENODEV, which causes log spam.
Register the power supplies only after we received some notification
indicating battmgr is ready to take off.

This driver uses delayed work to perform periodic battery state read out.
This delayed work is not stopped across suspend and resume cycle. The
read out can occur early in the resume cycle. In case of an I2C variant
of this hardware, that read out triggers I2C transfer. That I2C transfer
may happen while the I2C controller is still suspended, which produces a
WARNING in the kernel log.
Fix this by introducing trivial PM ops, which stop the delayed work before
the system enters suspend, and schedule the delayed work right after the
system resumes.

Pull USB/Thunderbolt updates from Greg KH:
"Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for
new hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio,
spi, and i2c drivers for that type of device (all acked by the
respective subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems"

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect bdi->model_name to be NUL-terminated based on its usage with
sysfs_emit and format strings:
val->strval is assigned to bdi->model_name in
bq24190_charger_get_property():
1186 | val->strval = bdi->model_name;
... then in power_supply_sysfs.c we use value.strval with a format string:
311 | ret = sysfs_emit(buf, "%s\n", value.strval);
we assigned value.strval via:
285 | ret = power_supply_get_property(psy, psp, &value);
... which invokes psy->desc->get_property():
1210 | return psy->desc->get_property(psy, psp, val);
with bq24190_charger_get_property():
1320 | static const struct power_supply_desc bq24190_charger_desc = {
...
1325 | .get_property = bq24190_charger_get_property,
Moreover, no NUL-padding is required as bdi is zero-allocated in
bq24190_charger.c:
1798 | bdi = devm_kzalloc(dev, sizeof(*bdi), GFP_KERNEL);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

power_supply_uevent() which is called to emit a udev event on device
deletion attempts to use the power_supply_battery_info structure,
which is device-managed and has been freed before this point.
Fix this by not generating all battery/charger properties when the
device is about to be removed. This also avoids generating errors
when trying to access the hardware in hot-unplug scenarios.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove

returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
