flchip_shared spinlock into a mutex. This should be save since no atomic
path will use this lock.

According to the Dell/Ubuntu driver, what was previously observed as
"jumpy cursor" corresponds to the hardware sending incorrect data for
the first two reports of a one touch finger. So let's use the same
workaround as in the other driver. Also, detect another firmware
version with the same behaviour, as in the other driver.

sil164 and friends are the most common, usually they just need to be

Unfortunately, BIOS scripts are useless here.

This patch moves two functions from .devexit to .text,
which are called on the probe error path.
Also a function which is called by probe is moved
from .text to .devinit.
WARNING: vmlinux.o(.devinit.text+0x2ca5): Section mismatch in reference
from the function via_pci_probe() to the function
devexit.text:via_teardown_subdevs()
The function __devinit via_pci_probe() references
a function __devexit via_teardown_subdevs().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
via_teardown_subdevs() so it may be used outside an exit section.
WARNING: vmlinux.o(.devinit.text+0x2cb1): Section mismatch in reference

Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event.
For driver binding/unbinding we with this in
place have the following bus notifier events:
- BUS_NOTIFY_BIND_DRIVER - before ->probe()
- BUS_NOTIFY_BOUND_DRIVER - after ->probe()
- BUS_NOTIFY_UNBIND_DRIVER - before ->remove()
- BUS_NOTIFY_UNBOUND_DRIVER - after ->remove()
The event BUS_NOTIFY_BIND_DRIVER allows bus code
to be notified that ->probe() is about to be called.
Useful for bus code that needs to setup hardware before
the driver gets to run. With this in place platform
drivers can be loaded and unloaded as modules and the
new BIND event allows bus code to control for instance
device clocks that must be enabled before the driver
can be executed.
Without this patch there is no way for the bus code to
get notified that a modular driver is about to be probed.
