V4L1 API is depreciated and should be removed soon from kernel. This patch
adds two new options, one to disable V4L1 drivers, and another to disable
V4L1 compat module. This way, it would be easy to check what still depends
on V4L1 stuff, allowing also to test if app works fine with V4L2 only support.

The computation in cx88_risc_buffer suffers from the mistake:
a non-zero padding value can cause more page borders to be crossed,
leading to big buffer over-runs.

It also changees the constant in cx88_risc_databuffer from 3 + 4 to 2,

It looks like the HD3000 was prototyped with the 7610 tuner when
the driver was developed, but the cards appear to have always shipped
with the 7612 tuner and the driver was never adjusted for it.
The definition needs to be corrected.
- The HD-3000 was prototyped with a Thomson DTT7610,
  but production versions used a DTT7612 tuner.
- This patch changes both dvb-pll settings and V4L tuner type.

This mutex is meant to stop two devices getting the same ID. dvbdev_get_free_id() 
scans the list of already allocated devices to find a free id.
Unfortunately, since the mutex is unlocked before the card is added to the
above list, it is still possible for two of them to get the same id.
Its debatable whether this mutex lock is actually needed, but I'm unwilling
to just remove it in case something does depend on it.

There are tree mistakes on bttv_risc_overlay.
1) When skip_odd is true, the number of lines for which
instructions are written is (height+1)/2, not height/2.
2) This occurs when clipping: the number of instruction bytes
written can be as much as 8 + 12*nclips, not 8 + 8*nclips, as
currently estimated.
3) Coverity check were wrong with nskips=0, since it means that
it can clipped at most one line.

This reverts commit 56cf6504.

Both Erik Mouw and Andrew Vasquez independently pinpointed this commit
as causing problems, where the slab cache for a driver is never released
(most obviously causing problems when immediately re-loading that
driver, resulting in a "kmem_cache_create: duplicate cache <xyz>"
message, but it can also cause other trouble).

James Bottomley dug into it, and reports:

  "OK, here's the scoop.  The problem patch adds a get of driverfs_dev in
   add_disk(), but doesn't put it again until disk_release() (which occurs
   on final put_disk() of the gendisk).

   However, in SCSI, the driverfs_dev is the sdev_gendev.  That means
   there's a reference held on sdev_gendev  until final disk put.
   Unfortunately, we use the driver model driver_remove to trigger
   del_gendisk (which removes the gendisk from visibility and decrements
   the refcount), so we've introduced an unbreakable deadlock in the
   reference counting with this.

   I suggest simply reversing this patch at the moment.  If Russell and
   Jens can tell me what they're trying to do I'll see if there's another
   way to do it."

so hereby the patch gets reverted, waiting for a better fix.

I introduced this way back in 2.6.13 when adding the port lock logic.
This device talks out through different "ports" all at the same time, so
the lock logic was wrong, preventing any data from ever being sent

If serial_open() fails at the port assignment or mutex_lock_interruptible()

If the device is disconnected while serial_open() is executing and
either try_module_get() or the device specific open function fails, the
kref_put() call in the 'bailout_kref_put' label will free the memory
pointed out by 'port'.

The subsequent dereferences in the 'bailout_kref_put' label will be
invalid.

The fix is just to assure kref_put() is called after any 'port' usage.

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time.  The bug is seen as a hung USB box and the kernel error:

drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110

The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued.  This affects only device startup.

Don't recurse back into the driver even if the unplug threshold is met,
when the driver asks for a requeue. This is both silly from a logical
point of view (requeues typically happen due to driver/hardware
shortage), and also dangerous since we could hit an endless request_fn
-> requeue -> unplug -> request_fn loop and crash on stack overrun.

Also limit blk_run_queue() to one level of recursion, similar to how
blk_start_queue() works.

This patch fixed a real problem with SLES10 and lpfc, and it could hit
any SCSI lld that returns non-zero from it's ->queuecommand() handler.
