James,
Please apply the following patches to the scsi tree, misc branch at your
earliest convenience.
These patches are on top of our earlier patchset:-
http://marc.info/?l=linux-scsi&m=137665441602732&w=2
Santosh Vernekar (2):
qla4xxx: Add pex-dma support for capturing minidump
qla4xxx: Fix the minidump data collection check in for loop
Vikas Chaudhary (2):
qla4xxx: Return error if minidump data collection fails
qla4xxx: Update driver version to 5.04.00-k1
Thanks,
Vikas.
