PCMCIA abuses dev->private_data in the probe methods. Unfortunately it
continues to abuse it after calling drv->probe() which leads to crashes and
other nasties (such as bogus probes of multifunction devices) giving errors like

pcmcia: registering new device pcmcia0.1
kernel: 0.1: GetNextTuple: No more items

Extract the passed data before calling the driver probe function that way
we don't blow up when the driver reuses dev->private_data as its right.

As its close to the final release just move the hack so it works out,
hopefully someone will be sufficiently embarrassed to produce a nice rework
for 2.6.28.

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.

Instead of using own error or success codes, the PCMCIA code should rely on

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

PCI drivers have the new_id file in sysfs which allows new IDs to be added
at runtime.  The advantage is to avoid re-compilation of a driver that
works for a new device, but it's ID table doesn't contain the new device.
This mechanism is only meant for testing, after the driver has been tested
successfully, the ID should be added in source code so that new revisions
of the kernel automatically detect the device.

The implementation follows the PCI implementation. The interface is documented
in Documentation/pcmcia/driver.txt. Computations should be done in userspace,
so the sysfs string contains the raw structure members for matching.

Some Elan serial cards allow for four (independent) multifunction

Signed-off-by: NDominik Brodowski <linux@dominikbrodowski.net>

s->functions needs to be initialized earlier, for the "let's see
how high it increases" approach means that pcmcia_request_irq()
(which makes use of this value) is confused, and might request
an exclusive IRQ first even though it is not supposed to.

Also, a CIS override autoloaded using the firmware loader may
allow for the use of more or less functions in a multifunction
card. Therefore, we may need to schedule a call to add this
second function later on, or simply remove the other function
(it's always the first -valid- function which reaches this
codepath).
