Subject: [PATCH] mv_sas: OCZ RevoDrive3/zDrive R4 support (completely untested)

From: "Robin H. Johnson" <robbat2@...too.org>

NOT FOR COMMIT USE; TESTING ONLY; NO WARRANTY; DANGER!

A friend recently bought a OCZ RevoDrive3 and was surprised by the lack
of Linux support. I glanced at the Windows driver .inf file for the
device, as well as the Windows driver for the zDrive R4, it looks like
rebranded mvsas (mostly based on earlier versions of the Windows driver
that include PCI IDs already found in the mvsas code).

I constructed this patch for my friend to test, completely blind.
I haven't heard back from him at all yet, but I thought that the wider
community might find it useful for testing as well. I think it _should_
work, just need to figure out what the correct chip variant is.
