I'm having problems getting the sata_mv driver working as a platform
driver on the QNAP TS-209 and the Linkstation/Kurobox (both are Marvell
Orion 88f5182 based devices). First of all it would oops in
mv_port_start() while calling dma_pool_alloc(), the patch to fix this is
at the end of this email.

Ouch.  I'd say this is proof-positive that Saeed did not even test his
latest patches.  Your fix below looks straightforward and correct.

Subject: [PATCH] sata_mv: platform driver allocs dma without create

When the sata_mv driver is used as a platform driver,
mv_create_dma_pools() is never called so it fails when trying
to alloc in mv_pool_start().
