2.26.02.000 - Driver cleanup for kernel submission.
2.26.02.001 - Replace schedule_timeout() calls with msleep().
+ 2.26.02.002 - Add support for PAE mode.
+ Add lun support.
+ Fix twa_remove() to free irq handler/unregister_chrdev()
+ before shutting down card.
+ Change to new 'change_queue_depth' api.
+ Fix 'handled=1' ISR usage, remove bogus IRQ check.
+ Remove un-needed eh_abort handler.
+ Add support for embedded firmware error strings.
