Linus Torvalds df49fd0ff8 SCSI fixes on 20190302 
Nine small fixes.  The resume fix is a cosmetic removal of a warning
 with an incorrect condition causing it to alarm people wrongly.  The
 other eight patches correct a thinko in Christoph Hellwig's DMA
 conversion series.  Without it all these drivers end up with 32 bit
 DMA masks meaning they bounce any page over 4GB before sending it to
 the controller.  Nowadays, even laptops mostly have memory above 4GB,
 so this can lead to significant performance degradation with all the
 bouncing.
