Tejun Heo 33480a0ede [PATCH] libata: don't initialize sg in ata_exec_internal() if DMA_NONE (take #2) 
Calling sg_init_one() with NULL buf causes oops on certain
configurations.  Don't initialize sg in ata_exec_internal() if
DMA_NONE and make the function complain if @buf is NULL when dma_dir
isn't DMA_NONE.  While at it, fix comment.

The problem is discovered and initial patch was submitted by Arnd
Bergmann.
