Re: [PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

[Dan MacDonald <allcoms@gmail.com>]

Hi all

Up until now I've only ever used the most basic features of git, so
I've had to do some research into how to best/cleanly extract
Phillipps patches so that I can include his changes into an Arch
kernel PKGBUILD.

I think the following should work:

git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git fetch https://git.pengutronix.de/git/pza/linux.git
tags/v4.10-ipu-dp-plane-fix
git checkout FETCH_HEAD
git whatchanged -p origin/master..FETCH_HEAD > sabre-lite.patch

I should then be able to include that patch in a 4.11-rc4 PKGBUILD -
I'll give it a go this weekend and see if it applies and builds OK but
please let me know if anyone sees any flaws in this procedure.

Thanks
