Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.
Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.

There is a strange chip at 0x2e on the second SMBus channel of the
DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the
system. As there's nothing interesting on this SMBus channel, the
easiest and safest thing to do is to disable it on that board.
This is a better fix to bug #5889 than the it87 driver update that was
done originally:

The use of cli()/sti() within the do/while was a way to ensure
interrupts were only disabled for short periods of time while the bulk
of the time interrupts were free to occur. The use of the spin lock
has eliminated the need to play with interrupts in this way while
still allowing for IO to be protected.
The remaining 3 sti() calls seem unneeded now that at no other point
in the driver is there a call to cli().

It is possible that the entry in sysfs already exists, one case of this is
when a network device is renamed to bonding_masters. Anyway, in this case
the proper error path is for device_rename to return an error code, not to
generate bogus backtrace and errors.
Also, to avoid possible races, the create link should be done before the
remove link. This makes a device rename atomic operation like other renames.

As setting and clearing queue flags now requires that we hold a spinlock
on the queue, and as blk_queue_stack_limits is called without that lock,
get the lock inside blk_queue_stack_limits.
For blk_queue_stack_limits to be able to find the right lock, each md
personality needs to set q->queue_lock to point to the appropriate lock.
Those personalities which didn't previously use a spin_lock, us
q->__queue_lock. So always initialise that lock when allocated.
With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no
longer cause warnings as it will be clear that the proper lock is held.

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but
work fine without one. This adds (priority functional) IRQ-less options
for each port option to help systems with few available IRQs.
The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ. Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front, not
back.
Doesn't use pnp_register_port_resource() for symetry with above.
This does not delete the AD1815 independent option even though it should
be empty after the IRQ transfer due to AD1816 coming with an empty but
still present independent option by default.
Was tested on AD1815, AD1816 and AZT2320. The ALSA snd-ad1818a driver
also support the AZT2002 ID for MPU401 but this doesn't as I was unable to
test it.

The following patch caused a regression with OLPC panels:
commit 3888d4639e
lxfb: extend PLL table to support dotclocks below 25 MHz
Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some
intermediate steps between pre-existing frequencies.
The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched. This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.
