Someone sent this same fix in before you did, a few days ago.  Be sure
to always use the most up-to-date tree.

sorry,

Please ignore previous email. It contains HTML.

Noted and thanks Greg.

A quick question, I just updated my linux-next tree last night,
checkout tag "next-20170210" and working on the cleanup. How do I
double check my current working file already been updated by someone
else to avoid the duplicate work? As of now, the latest linux-next
tree tag is still "next-20170210"

I am on eudyptula challenge and this is my first attempt to send
kernel patch, sorry about the silly question ;)

linux-next is usually a day or so behind my tree, due to the time
differences when it is created and why I usually do work.

You can work off of my staging-next branch in my staging.git tree on
git.kernel.org, that is the most up-to-date branch that ends up in
linux-next.  I also use staging-testing, to test things, but I would not
recommend that for you as it can be rebased and would be a pain to work
against.

It's ok that conflicts happen, that's how kernel development works,
sometimes people send in the same change minutes from each other, so I
have to take the one that was sent first.  It's ok, just move on and
work on something else if you really want to.

It's not silly, it comes up all the time.

good luck!

Thanks for the kind advice.

I will look up your staging-next branch and do something about it.

Talk to you soon.
