Subject: linux-next: build warnings after merge of the block tree

Hi Jens,

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

In file included from drivers/misc/cardreader/rts5209.c:24:0:
include/linux/rtsx_pci.h:40:0: warning: "SG_END" redefined
 #define   SG_END   0x02

and many more the same.
