Subject: linux-next: build warning after merge of the scsi tree

Hi all,

After merging the scsi tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from include/linux/pci-dma-compat.h:8,
                 from include/linux/pci.h:2408,
                 from drivers/scsi/mvumi.c:13:
drivers/scsi/mvumi.c: In function 'mvumi_queue_command':
include/linux/dma-mapping.h:608:34: warning: 'sg' may be used uninitialized in this function [-Wmaybe-uninitialized]
 #define dma_unmap_sg(d, s, n, r) dma_unmap_sg_attrs(d, s, n, r, 0)
                                  ^~~~~~~~~~~~~~~~~~
drivers/scsi/mvumi.c:192:22: note: 'sg' was declared here
  struct scatterlist *sg;
                      ^~

Introduced by commit
