[SCSI] aacraid: Correct sa platform support. (Was: [Bug 8469] Bad EIP value on pentium3 SMP kernel-2.6.21.1)

http://bugzilla.kernel.org/show_bug.cgi?id=8469



As discussed in the bugzilla outlined below, we have an sa based
(Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected
controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec
5400S. This problem  coincides with the introduction of the adapter_comm
and adapter_deliver platform functions (Message [PATCH 1/4] aacraid:
rework communication support code, January 23 2007, which initially
migrated to 2.6.21)

The panic occurs with an uninitialized adapter_deliver platform function
pointer. The enclosed patch, unmodified as tested by Rainer, solves the
problem.
