linux-next: build failure after merge of the final tree (staging tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/staging/silicom/bypasslib/built-in.o: In function `.is_bypass':
(.text+0x3254): multiple definition of `.is_bypass'
drivers/staging/silicom/bpctl_mod.o:(.text+0x1d938): first defined here
drivers/staging/silicom/bypasslib/built-in.o: In function `is_bypass':
(.opd+0x480): multiple definition of `is_bypass'
drivers/staging/silicom/bpctl_mod.o:(.opd+0x15f0): first defined here

Caused by commit 7040e556c90a ("staging: add Silicom Bypass driver").

I added this patch to disable the driver:

I think forcing this driver to be a module will resolve this issue.
It seems to be quite a common problem for most staging drivers when they
first land in the tree, sorry for not catching this one.

This doesn't make sense in a changelog entry.

This needs to be in the Subject: line of the patch, don't make me edit
it by hand to add it in.

You forgot to add:
	Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
to this list, as he is the one that found the problem.

Care to fix this up and resend the patch so I can apply it without
needing to edit it at all?

thanks,
