Subject: cciss: fix XFER_READ/XFER_WRITE in do_cciss_request
From: Mike Miller <mike.miller@xxxxxx>
Fix a stupid bug. Sometime during the 2tb enhancement I ended up replacing
the macros XFER_READ and XFER_WRITE with h->cciss_read and h->cciss_write
respectively. It seemed to work somehow at least on x86_64 and ia64. I don't
know how. But people started complaining about command timeouts on older
controllers like the 64xx series and only on ia32. This resolves the issue
reproduced in our lab. Please consider this for inclusion.
