Hi Rafael,

After merging the suspend tree, today's linux-next build (x86_64
allmodconfig) failed like this:

net/mac80211/scan.c: In function 'ieee80211_scan_state_decision':
net/mac80211/scan.c:510: error: implicit declaration of function 'pm_qos_requirement'

Caused by commit 62bad14fc6e0911a99882c261390968977d43283 ("PM QOS
update") from the suspend tree interacting with commit
df13cce53a7b28a81460e6bfc4857e9df4956141 ("mac80211: Improve software
scan timing") from the net tree.

I have added the following merge fixup patch and can carry it as
necessary:

Thanks a lot, please do so if that's not a problem.

Both trees are based on Linus' current and I don't see a good way of fixing
this issue in any of them individually.

Hi John, Dave,


The suspend tree has been merged into Linus' tree, so this patch is
needed in the net tree before it is merged (or as part of the merge).

Here is the patch again:

Since the net tree is still on it's way to Linus, we'll just have to
wait for him to do that merge.

Then we can sort this out.  I don't want to touch a tree that is
already on it's way.

Thanks Stephen.

Linus merged your tree David.

This must have happened in the past hour :-)

Great, I can sort this now.
