[GIT PATCH] SCSI bug fixes for 2.6.24-rc5

[James Bottomley <James.Bottomley@SteelEye.com>]

This patch series is a sequence of late arriving bug fixes, mainly in
drivers but also one debugging scatterlist BUG_ON() in the tape ULD.
The initio bug fixes are definitely required, we just don't have
confirmation that they're the whole fix yet, so an additional fix for
initio may be necessary.

The patch is available at:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git

The short changelog is:

Alan Cox (1):
      initio: fix conflict when loading driver

Boaz Harrosh (1):
      initio: bugfix for accessors patch

FUJITA Tomonori (1):
      st: fix kernel BUG at include/linux/scatterlist.h:59!

James Bottomley (1):
      dpt_i2o: driver is only 32 bit so don't set 64 bit DMA mask

Tony Battersby (2):
      sym53c8xx: fix "irq X: nobody cared" regression
      sym53c8xx: fix free_irq() regression
