A previous patch changed VBI_OFFSET to match what the datasheets say it
should be. However, the bt8x8 datasheets are wrong. The old value of
244 is closer to what is actually observed. The real value appears to
not be constant and is different for different chip revisions.

Add proper error checking and roll-back for failure of
class_device_create_file() in videodev.c. Print error messages and
unroll partially created sysfs entries.
Also, failure of class_device_register() in video_register_device() is
handled correctly. It was failing to de-allocate the minor number. This
must be done in video_register_device(), since the caller has no way of
knowing if failure occurred before or after the class device was
registered.
Also added an error message if video_register_device() is called with
an unknown type, which should never happen.

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

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 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.

Implement ahci_[de]init_port() and use it during initialization and
de-initialization. ahci_[de]init_port() are supersets of what used to
be done during driver [de-]initialization. This patch makes the
following behavior changes.
* Per-port IRQ mask is cleared on driver load as done in other
drivers. The mask will be configured properly during probe.
* During init_one(), HOST_IRQ_STAT is cleared after masking port IRQs
such that there is no race window.
* CMD_SPIN_UP is cleared during init_one() instead of being set. It
is set in port_start(). This is more consistent with overall
structure of initialization. Note that CMD_SPIN_UP simply controls
PHY activation.
* Slumber and staggered spin-up are handled properly.
* All init/deinit operations are done in step-by-step manner as
described in the spec instead of issued as single merged command.

Simplify ahci_start_engine() by killing prerequisite condition checks.
Rationales are..
* No user checks error return from ahci_start_engine()
* Code flow guarantees the prerequisite conditions unless the
controller is malfunctioning. In such cases, the driver had chances
to learn about the problem _before_ calling this function.
* Closely related to the above two, driver calls into this function
even when prerequisites fail hoping for the best.
Basically, ahci_start_engine() should only do the operation itself.
It isn't the right place to check for prerequisites.
