tree-wide: use reinit_completion instead of INIT_COMPLETION
Use this new function to make code more comprehensible, since we are

jz4740-battery: Remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release or on
probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is
not needed to manually clear the device driver data to NULL.

workqueue: use mod_delayed_work() instead of cancel + queue
Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().
Most conversions are straight-forward. Ones worth mentioning are,
* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
use mod_delayed_work() and cancel loop in
edac_mc_reset_delay_period() is dropped.
* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
watchdog is active or not. @fan_watchdog_active and related code
dropped.
* drivers/power/charger-manager.c: Seemingly a lot of
delayed_work_pending() abuse going on here.
[delayed_]work_pending() are unsynchronized and racy when used like
this. I converted one instance in fullbatt_handler(). Please
conver the rest so that it invokes workqueue APIs for the intended
target state rather than trying to game work item pending state
transitions. e.g. if timer should be modified - call
mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().
* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
simplified. Note that round_jiffies() calls in this function are
meaningless. round_jiffies() work on absolute jiffies not delta
delay used by delayed_work.
v2: Tomi pointed out that __cancel_delayed_work() users can't be
safely converted to mod_delayed_work(). They could be calling it
from irq context and if that happens while delayed_work_timer_fn()
is running, it could deadlock. __cancel_delayed_work() users are
dropped.

jz4740-battery: Should include linux/io.h
During test-build (with disabled 'depends on') I found that
jz4740-battery driver lacks linux/io.h, which makes build break
like this (on x86):
CC [M] drivers/power/isp1704_charger.o
jz4740-battery.c: In function 'jz_battery_read_voltage':
jz4740-battery.c:84: error: implicit declaration of function 'readw’
jz4740-battery.c: In function 'jz_battery_probe':
jz4740-battery.c:284: error: implicit declaration of function 'ioremap_nocache’
jz4740-battery.c:285: warning: assignment makes pointer from integer without a cast
jz4740-battery.c:372: error: implicit declaration of function 'iounmap'
make[2]: *** [drivers/power/jz4740-battery.o] Error 1
This patch fixes the issues, and thus makes it easier to build-test
the driver for me.
