16735d022f tree-wide: use reinit_completion instead of INIT_COMPLETION
Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

3ed5cd79b8 bq2415x_charger: Fix max battery regulation voltage
As per the datasheets, maximum battery regulation voltage is 4440mV.

The formula is (voltage - offset) / step, so the maximum value is:
(4440 - 3500) / 20 = 47

db15e6312e rx51_battery: Fix channel number when reading adc value
This issue was introduced in commit 8e2747f031 "power: rx51_battery:
Replace hardcoded channels values."

Original code use channel as argument which was shifted by one in
function. After mentioned commit argument is already shifted so we need to
get index back.

d24fed391d bq24190_charger: Workaround SS definition problem on i386 builds
For __i386__ builds we have:

arch/x86/include/uapi/asm/ptrace-abi.h:#define SS   16

And in the driver:

BQ24190_SYSFS_FIELD_RO(vbus_stat,       SS,     VBUS_STAT)

That breaks the build like this:

drivers/power/bq24190_charger.c:375:138: error: ‘BQ24190_REG_16’
undeclared here (not in a function)
drivers/power/bq24190_charger.c:375:162: error:

drivers/power/bq24190_charger.c:375:203: error:
‘BQ24190_REG_16_THERM_STAT_SHIFT’ undeclared here (not
 in a function)

With this commit we workaround the problem by undefining 'SS'.

948dcf9662 power_supply: Prevent suspend until power supply events are processed
This patch, originally authored by Arve Hjonnevag and Todd Poynor,
prevents the system from entering suspend mode until the power supply
plug, unplug, or any other change of state event is fully processed. This
guarantees that the screen lights up and displays the battery charging
state. The implementation uses the power supply wakeup_source object.
