We add a check of the return value of tty_ldisc_ref(), which
is checked 7 out of 8 times, e.g.:

149  		ld = tty_ldisc_ref(tty);
150  		if (ld != NULL) {
151  			if (ld->set_termios)
152  				(ld->set_termios)(tty, &old_termios);
153  			tty_ldisc_deref(ld);
154  		}

This defect was found automatically by Coverity Prevent, a static analysis
tool.

(akpm: presumably `ld' is never NULL.  Oh well)

Changed hue offset to 128 to correct behavior in cx88 cards.  Previously,
setting 0% or 100% hue was required to avoid blue/green people on screen.
Now, 50% Hue means no offset, just like bt878 stuff.

A problem was reported that the tpm driver was interfereing with
networking on the 8139 chipset.  The tpm driver was using a hard coded
the memory address instead of the value the BIOS was putting the chip
at.  This was in the tpm_lpc_bus_init function.  That function can be
replaced with querying the value at Vendor specific locations.  This
patch replaces all calls to tpm_lpc_bus_init and the hardcoding of the
base address with a lookup of the address at the correct vendor
location.

Drivers really only work well in SMP if they actually can be selected.
This is a leftover from the time when the 6pack drive only used to be
a bitrotten variant of the slip driver.

[SHAPER]: Switch to spinlocks.

Dave, you were right and the sleeping locks in shaper were
broken. Markus Kanet noticed this and also tested the patch below that
switches locking to spinlocks.

If ACPI doesn't find an irq listed, don't accept 0 as a valid PCI irq.
That zero just means that nothing else found any irq information either.

ACPI: Make sure we call acpi_register_gsi() even for default PCI interrupt assignment

That's the part that keeps track of the ELCR register, and we want to
make sure that the PCI interrupts are properly marked level/low.

This patch fixes an obvious and nasty bug where we could exit the transmit

Return to previous held-logic of calling scsi_add_host() only
after the board has been completely initialized.  Also return
pci_*() error-codes during probe failure paths.

This also corrects an issue where only lun 0 is being scanned for
a given port.
