void
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
callback to the void returning variant.

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.

While scanning the internet for MM8013 PDFs, I found one for a different
IC from Mitsumi, MM8118 at [1]. It turned out however, that when you
search through the PDF, the MM8118 text has an invsible text layer
containing "MM8013" underneath..
With some elbow grease, I was able to confirm that most of the registers
match between the two ICs. Based on that finding, introduce live battery
voltage readout, hw-decided charge behavior readout and max current
readout. Also, expand the existing POWER_SUPPLY_HEALTH reporting.

pm8916 LBC is a Linear Battery Charger hardware block in pm8916 PMIC.
This block implements simple CC/CV charging for Li-Po batteries.
The hardware has internal state machine to switch between modes and
works mostly autonomously, only needing the limits and targets to be
set to operate.
This driver allows setting limits and enabling the LBC block, monitoring
it's state.

This driver adds basic support for VM-BMS found in pm8916.
VM-BMS is a very basic fuel-gauge hardware block that is, sadly,
incapable of any gauging. The hardware supports measuring OCV in
sleep mode, where the battery is not in use, or measuring average
voltage over time when the device is active.
This driver implements basic value readout from this block.

Ensure that the dynamically created power supply device sets its
->of_node if the driver supplies one. This brings it in line with
several other subsystems (see git grep 'of_node =.*parent.*of_node') and
allows easier identification of the device from udev rules and similar.
Before this patch:
