883730c192 power: supply: wm831x: Constify struct chg_map and some arrays
'struct chg_map' is not modified in this driver.

Constifying these structures moves some data to a read-only section, so
increase overall security.

While at it, also constify a few other arrays.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  14263	   1744	      0	  16007	   3e87	drivers/power/supply/wm831x_power.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  14695	   1288	      0	  15983	   3e6f	drivers/power/supply/wm831x_power.o

83bce34420 power: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/power/ 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.

While touching these files, make indention of the struct initializer
consistent in several files.

f2a7667c6c power: supply: wm831x: Use devm_power_supply_register() helper
Use the device lifecycle managed register function. This helps prevent
mistakes like unregistering out of order in cleanup functions and
forgetting to unregister on error paths.

dab68bbb54 power: supply: wm831x_power: Convert to platform remove callback returning 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.

df561f6688 treewide: Use fallthrough pseudo-keyword
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary

identified by the USB stack, allowing us to charge more quickly from high

8c0984e5a7 power: move power supply drivers to power/supply
This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
