This patch fixes a nasty typo in usbtouchscreen driver. The typo
is inherited from the original mtouchusb. It used to make the input
subsytem to incorrectly report the physical device ids to userspace
that in turn is very confusing for, e.g. XInput hotplug facilities
in setups with multiple identical touchscreens.

The appletouch geyser3 devices found in the Intel Macs (and possibly
some later PPC ones?) send a constant stream of packets after the first
touch. This results in the kernel waking up around once every couple of
milliseconds to process them, making it almost impossible to spend any
significant amount of time in C3 state on a dynamic HZ kernel. Sending
the mode initialization code makes the device shut up until it's touched
again. This patch does so after receiving 10 packets with no interesting
content.

On some boxes that don't have PS/2 mice connected at startup BIOS
completely disables AUX port and attempts to access it result in
hosed keyboard. Historically we do not trust ACPI/PNP data on
i386 and try to poke AUX port even if we did not find an active
PNP node for it. However in cases when BIOS writers got KBD port
properly described we can assume that they did the right thing
for AUX port as well.

These serial touchscreens are found on some Fujitsu lifebook
P-series laptops, and the B6210. Using this requires a new

work on his B6210 laptop.

Pendown status from the PENIRQ pin is currently read only at the beginning
of a sample set. If the pen is lifted just after sampling has began then
sampled values become wrong.
This patch adds an optional platform penirq_recheck_delay attribute. If
non-zero, samples are only reported to the input subsystem if PENIRQ is
still active that long after the samples taken.

The ads7846 driver has support for filtering, but when the chip gets
deselected between samples this causes noise. This patch adds support
for an optional settling delay time, so that two consecutive samples
will be taken with the specified delay time apart. This ensures that
the chip won't be deselected, so the noise won't appear.
Filtering can still be done, but will have less work to do since each
time a new sample is taken the same delay applies.

Export LEDs on Xbox360 pad via led subsystem as a single device in
/sys/class/leds/xpad[0-9]+.
Xbox360 pad has four leds, which form a circle. Unfortunately the leds
can't be controlled independently and can only display a predefined
set of patterns (for example one is turned on wile others are off or
a rotating pattern - 1-2-3-4). To activate a pattern one needs to send
a specific command to the device (see http://www.free60.org/wiki/Gamepad).
Led subsystem allows us to set brightness, but there is nothing like
brightness on this device. So brightness is actually interpreted as
the command (only values between 0 and 14 are accepted).

The old IDE driver is not ready to take generic SCSI commands, even if
it uses them for some specific issues (ie the tray open/close ioctls for
IDE CD-ROM's). Pointed out by Bartlomiej.
I'm sure we'll have it fixed properly soon enough, but for now we should
not allow it to cause problems.

1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig.
2) Break up setup_netjet_s() into three separate internal functions.
This helps facilitate upcoming use of PCI hotplug API, and in addition
makes the code much easier to follow.
No code is changed, just moved around. I even kept the out-of-favor
"return(0)" style used in the current source code.

Initializing 'f0' is not strictly necessary in either case, AFAICS.

complex flow of control in each function, I feel it is wiser and
safer to simply zero the var and be certain of ourselves.
