when usb-type tuner is pulled out, user applications did not close device's FD,
and go on polling the device, we should return POLLERR directly.

Data type of return value is unsigned int, but in function of dvb_demux_poll,
when the pointer of dmxdevfilter equals NULL, it will return -EINVAL, which
is invalid.

Normally, ADAP_STREAMING bit is set in dvb_usb_start_feed and cleared in
dvb_usb_stop_feed.
But in exceptional cases, for example, when the tv is playing programs
and the tuner is pulled out, then dvb_usbv2_disconnect is called.
In such case, it will first call dvb_usbv2_adapter_frontend_exit to stop
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:

governor to use the maximal cooling state just after crossing

the full speed of FAN which is noisy and not really necessary.

This patch add new 'load_table' debugfs file to show previous accumulated data
of CPUs load as following path and add CPUFREQ_LOADCHECK notification to
CPUFREQ_TRANSITION_NOTIFIER notifier chain.
- /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
accumulates calculated CPUs load on 'load_table' storage.
This debugfs file is used to judge the correct system state or determine
suitable system resource according to current CPUs load on user-space.
This debugfs file include following data:
- Measurement point of time
- CPU frequency
- Per-CPU load
Changes since v6:
- Remove unnecessary memory free/allocation operation on
cpufreq_stats_reset_debugfs()
- Get correct index of cpu_debugfs[] array according to cpu number
- Reset 'load_table' data when cpufreq governor is changed or updated because
specific governor(e.g., performance/powersave) haven't used 'load_table;
debugfs file.
Changes since v5:
- Determine index value of policy->cpu_debugfs[] according to
cpumask_weight(policy->cpus) value
- 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
: [PATCH 1/2] cpufreq: Add debugfs directory for cpufreq
Changes since v3:
- Extend a range of accumulated data (10 ~ 1000)
- 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
new: /sys/kernel/debugfs/cpufreq/cpuX/load_table
Changes since v1:
- Set maximum storage size to save CPUs load on Kconfig
- Use spinlock to synchronize read/write operation for CPUs load
- Use local variable instead of global variable(struct cpufreq_freqs *freqs)
- Use pointer of data structure to get correct size of data structure
in sizeof() macro instead of structure name
: sizeof(struct cpufreq_freqs) -> sizeof(*stat->load_table)
- Change time unit from nanosecond to microsecond
- Remove unnecessary memory copy

This patch create debugfs root directory and child directory according to
the number of CPUs for CPUFreq as below debugfs directory path:
- /sys/kernel/debug/cpufreq/cpuX
If many CPUs share only one cpufreq policy, other CPUs(except for first CPU)
create a symbolic link for debugfs directory of CPU0.
- link: /sys/kernel/debug/cpufreq/cpu[1-(N-1)] -> /sys/kernel/debug/cpufreq/cpu0
And then cpufreq may need to create debugfs specific file below of debugfs
directory of cpufreq. (e.g., /sys/kernel/debug/cpufreq/cpu0/load_table)
Changes since v6:
- Use 'policy->related_cpus' instead of 'policy->cpus' when getting the number
of CPUs included in the same package
- Get correct index of cpu_debugfs[] array according to cpu number
- Refactoring cpufreq_move_debugfs_dir() / cpufreq_create_debugfs_symlink()
- Use for_each_cpu() to support multi cluster instead of for_each_present_cpu()
Changes since v5:
- Refactoring patch v4
- Create again symbolic link of debugfs directory when first CPU dev is removed
(In this case, many CPUs share only one cpufreq policy)

This clock should be passed by default. If they are defined, then
these clocks will be masked in case that relevant drivers don't
enable them.

This reverts commit 3fce4fefb40c28cadc40d2fa3452121eb0240ec1.

Now that xc5000_set_params() is also called during resume,
move the code that checks for the firmware to happen there.
This way, the firmware will be loaded either for analog or
digital TV when .resume callback is called.

When DVB is streaming and suspend is called, it will call
au0828_stop_transport(), with will clean the streaming flag.
Due to that, stop_urb_transfer() will be called twice,
causing an oops.
So, we need another flag to be used at resume, telling it
to restart DVB.
While here, add a logic at stop_urb_transfer() to prevent
it of being called twice, and convert the usb_streaming
flag into boolean.

dev->dvb is always not null, as it is an area at the dev
memory. So, checking if (dev->dvb) is always true.
Instead of this stupid check, what the code wants to do is
to know if the DVB was successully registered.
Fix it by checking, instead, for dvb->frontend. It should
also be sure that this var will be NULL if the device was
not properly initialized.

xc5000_set_params() is a bad name for a function that
handles only digital TV. Rename it to xc5000_set_digital_params(),
and proper name the generic function that works for both
digital and analog.
No functional changes.

If a device suspends/hibertates with a station tuned, restore
the tuner station at resume.

As we need a function that reapply the last tuned radio,
in order to do resume, split the code that validates and
updates the internal priv struct from the ones that
actually set radio and TV.
A latter patch will add support for resume.

As we'll be adding a code to resume tuner operation, we
need to move the code that actually sets DTV on a separate
function, to be called by the resume code.
No functional changes, just code got moved.

After xc5000 stops working, it waits for 5 seconds, waiting
for a new usage. Only after that it goes to low power mode.
If a suspend event happens before that, a work queue will
remain active, with causes suspend to crash.
