Hi Stephen,

Today's linux-next merge of the bcm2835 tree got a conflict in
arch/arm/boot/dts/Makefile between commit 302a5ef29d49 ("ARM: BCM5301X:
Add DT for Netgear R6300 V2") from the arm-soc tree and commit
6298ed17a404 ("ARM: bcm2835: Add device tree for Raspberry Pi model
B+") from the bcm2835 tree.

I fixed it up (the bcm2835 tree patch is also in the arm-soc tree as
commit ba2a1d6959ac ("ARM: bcm2835: Add device tree for Raspberry Pi
model B+"), so I just used the arm-soc version) and can carry the fix
as necessary (no action is required).

Thanks a lot for the notification!

Lee, do you know what is going on? Did you accidentally rebase a commit
that you already sent for inclusion in arm-soc?

Nope. The branch hasn't changed at all.

OOI why would a re-base affect anything? I sent you it in patch form.

Ah, I looked at the wrong branch and didn't see that I applied a patch
instead of a pull request. It's all fine then, as long as you never
intend to send any pull requests based on top of your current branch.

You can possibly make Stephen's life a tiny bit simpler if you just
drop all patches from your for-next branch as soon as we've picked
them up into arm-soc.

That is something I thought about, but I believe we have users of that
branch. I guess we could always point them to ARM-SoC, or reset the
branch to the aforementioned.

The primary purpose of the kernel.org linux-rpi.git repo is for staging patches into arm-soc/linux-next. As such, just like any other similar repo, users should expect at least the for-xxx (e.g. for-next) branches to get reset as kernel versions tick over, in order to contain the content for the next kernel. Anyone using those branches for anything else (e.g. local development) simply has to be prepared to do a rebase themselves when that happens.

Equally, and patches that get sent to arm-soc should probably never be applied to linux-rpi.git; anything that gets applied to linux-rpi.git should get sent to arm-soc as a pull request. That avoids duplicate commits.
