sym53c8xx fixes

James, please consider these patches for inclusion in 2.6.29 or 2.6.30.

Patches 1 - 5 fix bugs found when auditing the error paths of sym53c8xx during module load and unload. These 5 patches must be applied in the order given, since they touch the same areas of the same file. Patches 6 and 7 fix other problems and annoyances, and can be applied in any order.

In addition, here are some related patches by other people that I would like applied:

The following patch fixes handling of errors that occur after scsi_host_alloc() during modprobe sym53c8xx. I actually came up with the same fix myself when auditing sym53c8xx, but a search of linux-scsi showed that someone else had already gotten there first. [PATCH] SCSI: fix /proc memory leak in the SCSI core

The following patch was posted a year ago but forgotten. I have been using it for a long time, and it still applies cleanly. sym53c8xx ISTAT1 feature never set

And of course there are the recent patches by Aaro Koskinen:
