Fix bug reported by Andrew de Quincey:
After cold boot the saa7146 DMA did not start if the demuxer was opened
before the frontend has locked to the signal.
DMA transfers will be started now if (and only if)
the frontend is locked and data should be sent to the demuxer.

Check __must_check warnings for class_device_register and class_device_create_file
video_device_create_file was declared as a void, but instead should
return the int value of class_device_create_file.
Move the check from bttv-driver.c into v4l2-dev.h, because all other
callers of video_device_create_file must also be checked.
Replace the call to class_device_create_file in videodev.c with
video_device_create_file, as defined in v4l2-dev.h, so that the
return value of class_device_create_file will be checked.
Check the return value of class_device_register in videodev.c and
pvrusb2-sysfs.c

With the LG H06xF tuners, an auxiliary byte must be sent after the
standard four-byte i2c sequence. The code that does this is currently in
the wrong place, causing random bytes to be written to the tuner over
i2c in the set_type function.
This patch moves this code from set_type to default_set_tv_freq.

The changes to add frontend reinitialisation moved the position where the
init() op is called into the frontend thread. Unfortunately, since DISEQC
operations do not use the frontend thread, this meant that DISEQC could be
called against an uninitalised frontend, leading to all sorts of trouble.
Patch fixes this by reinstating the original fronted intialisation call.

This patch (effectively Michael's patch with a couple of small

because it expects HALT I/O to alter the subchannel status which

This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.
The fas216 change is trivial, it should have been using ->cmnd all the
time.
NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake. Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.
And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.

The patch below moves the cpu hotplugging higher up in the cpufreq
layering; this is needed to avoid recursive taking of the cpu hotplug
lock and to otherwise detangle the mess.
The new rules are:
1. you must do lock_cpu_hotplug() around the following functions:
__cpufreq_driver_target
__cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only)
__cpufreq_set_policy
2. governer methods (.governer) must NOT take the lock_cpu_hotplug()
lock in any way; they are called with the lock taken already
3. if your governer spawns a thread that does things, like calling
__cpufreq_driver_target, your thread must honor rule #1.
4. the policy lock and other cpufreq internal locks nest within
the lock_cpu_hotplug() lock.
I'm not entirely happy about how the __cpufreq_governor rule ended up
(conditional locking rule depending on the argument) but basically all
callers pass this as a constant so it's not too horrible.
The patch also removes the cpufreq_governor() function since during the
locking audit it turned out to be entirely unused (so no need to fix it)
The patch works on my testbox, but it could use more testing
(otoh... it can't be much worse than the current code)
