Drop static on a local variable, when the variable is either first
initialized or never used, on every possible execution path through the
function. The static has no benefit, and dropping it reduces the code
size.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@bad exists@
position p;
identifier x;
type T;
@@
static T x@p;
...
x = <+...x...+>
@@
identifier x;
expression e;
type T;
position p != bad.p;
@@
-static
T x@p;
... when != x
when strict
?x = e;
// </smpl>
The change in code size is indicates by the following output from the size
command.

The X-Powers AXP20X PMIC exposes the current current and voltage
measures via an internal ADC.
This adds the possibility to read IIO channels directly for processed
values rather than reading the registers and computing the value.
For backward compatibility purpose, if the IIO driver is not compiled,
this driver will fall back on previous behaviour which is direct
register readings.

Casting of_device_get_match_data return value to int causes warning on 64bit
architectures.

The X-Powers AXP223 shares most of its behaviour with the AXP221 PMIC
but allows the VBUS power supply max current to be set to 100mA (like
the AXP209 PMIC).
This basically adds a new compatible to the VBUS power supply driver and
adds a check on the compatible when setting current max limit.

AXP20X and AXP22X PMICs allow setting the min voltage and max current of
VBUS power supply. This adds entries in sysfs to allow to do so.

This replaces calls to of_device_is_compatible to check data field of
of_device_id matched when probing the driver.

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.
