power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activate
power_supply_register() calls device_init_wakeup() to register a wakeup
source before initializing dev_name. As a result, device_wakeup_enable()
end up registering wakeup source with a null name when
wakeup_source_register() gets called with dev_name(dev) which is null at
the time.
When kernel is booted with wakeup_source_activate enabled, it will panic
when the trace point code tries to dereference ws->name.
Fixed the problem by moving up the kobject_set_name() call prior to
accesses to dev_name(). Replaced kobject_set_name() with dev_set_name()
which is the right interface to be called from drivers. Fixed the call to
device_del() prior to device_add() in for wakeup_init_failed error
handling code.

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.

dvb_frontend_thread, and then call dvb_usbv2_adapter_dvb_exit to clear
ADAP_STREAMING bit.
At this point, if dvb_frontend_thread is sleeping and waiting for
ADAP_STREAMING to be cleared to get out of sleep. then
dvb_frontend_thread can never be stoped, because clearing ADAP_STREAMING
bit is performed after dvb_frontend_thread is stopped (i.e. performed in
dvb_usbv2_adapter_dvb_exit).
So, deadlock:

- /sys/kernel/debug/cpufreq/cpuX/load_table
When governor calculates CPUs load on dbs_check_cpu(), governor send
CPUFREQ_LOADCHECK notification with CPUs load, so that cpufreq_stats

- CPU frequency
- Per-CPU load

- Get correct index of cpu_debugfs[] array according to cpu number
- Reset 'load_table' data when cpufreq governor is changed or updated because

debugfs file.
Changes since v5:
- Determine index value of policy->cpu_debugfs[] according to

- Bug fix, store 'policy->cpu' to 'freq->cpu' before notify
CPUFREQ_LOADCHECK notification
Changes since v4:
- Reset the data of CPUs load when cpufreq governor is changed
- Move code about creating debugfs directory to below first patch

- Add unit information of time/freq and align 'Time' field as left for readability
- Use CONFIG_CPU_FREQ_STAT depdendency instead of CONFIG_CPU_FREQ_STAT_DETATILS
- Initialize load of offline CPUx as zero(0)
- Create/remove debugfs root directory on cpufreq_stats_init/exit() because
debugfs root is used on all CPUs.
Changes since v2:
- Code clean according to Viresh Kumar's comment
- Show both old frequency and new frequency on 'load_table' debugfs file
- Change debufs file patch as below
old: /sys/kernel/debugfs/cpufreq/load_table
