[drivers/power/supply/ab8500_chargalg.c:493]: (style) Variable 'ab8500_chargalg_ex_ac_enable_toggle' is assigned a value that is never used.
From inspection, this variable is never used. So remove it.

The mt6370-charger driver uses IIO interfaces and produces build
errors when CONFIG_IIO is not set, so it should depend on IIO.

MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger
with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight
driver, display bias voltage supply, one general purpose LDO, and the
USB Type-C & PD controller complies with the latest USB Type-C and PD
standards.
Add support for the MediaTek MT6370 Charger driver. The charger module
of MT6370 supports High-Accuracy Voltage/Current Regulation,
Average Input Current Regulation, Battery Temperature Sensing,
Over-Temperature Protection, DPDM Detection for BC1.2.

Clang warns:
drivers/power/supply/bq25890_charger.c:625:40: error: implicit conversion from enumeration type 'enum bq25890_fields' to different enumeration type 'enum bq25890_table_ids' [-Werror,-Wenum-conversion]

~~~~~~~~~~~~~~~~ ^~~~~~~~
1 error generated.
Use the proper value from the right enumerated type, TBL_IINLIM, so
there is no more implcit conversion. The numerical values of F_IINLIM
and TBL_IINLIM happen to be the same so there is no change in behavior.

The driver has a lot of sparse warnings for using 0 as a NULL
pointer when NULL would be appropriate. Change the 0 values
to NULL to fix the warnings, some of which are shown here:

Let user set input current limit via sysfs. This is useful in case there
are multiple chargers connected to the device, each of which with its own
arbitrary maximum current which it can provide, some of which may provide
more than the default 500mA. In that case, userspace can listen for plug
events generated by each charger and adjust the current limit accordingly,
e.g. to permit battery to charge faster.
Note that the IINLIM is reset every time the bq25890 is disconnected from
a charger, so the userspace must adjust the limit repeatly on every plug
event.

Use devm_delayed_work_autocancel() instead of the INIT_DELAYED_WORK() to
remove the cw_bat_remove() function.
And power_supply_put_battery_info() can also be removed because the
power_supply_get_battery_info() uses device managed memory allocation.
