Hi, 

The patchset applied fine for me, but I'm getting do_patch errors when building:

*** Manual patch resolution mode ***
Dropping to a shell, so patch rejects can be fixed manually.
Run "quilt refresh" when patch is corrected, press CTRL+D to exit.

I actually fixed a couple of these up, but they keep coming...

So is there anything special I need to do to get this building cleanly?
I'm using master, and added the following to my local.conf:

GCCVERSION = "4.6.0"
SDKGCCVERSION = "4.6.0"

and did bitbake linux-yocto.


Once I have it working and can fix compile errors, I can send a patch to
fix it up if necessary, but note that this particular gcc warning
(unused-but-set-variable) is on its way to being disabled in the
upstream kernel.  See the lkml thread, "Re: annoying new gcc 4.6.0
warnings.":
