Subject: linux-next: build failure after merge of the staging tree

Hi Greg,

After merging the staging tree, today's linux-next build (powerpc
allyesconfig - I presume that an x86_64 allyesconfig will fail the
same way) failed like this:

drivers/staging/rtl8188eu/core/rtw_wlan_util.o: In function `.rtw_get_oper_ch':
(.text+0x9d0): multiple definition of `.rtw_get_oper_ch'
drivers/staging/rtl8723bs/core/rtw_wlan_util.o:(.text+0x9a0): first defined here

and many, many more ...

Presumably caused by commit

  554c0a3abf21 ("staging: Add rtl8723bs sdio wifi driver")

I guess this driver was copied from drivers/staging/rtl8188eu/ at some
point and modified (or they have the same ancestor) since they share a
large number of global symbols.

I have applied the following patch for today:
