"tipc: fix socket timer deadlock" to stable?

Hello,

We're seeing this tipc deadlock in 4.4.y, that was fixed in the mainline 
commit f1d048f24e66ba85d3dabf3d076cefa5f2b546b0 "tipc: fix socket timer 
deadlock".

Could/should this patch also be included in the stable kernel trees?

I just checked that the patch applies on top of 4.4.53, only the line 
numbers are different compared to the upstream commit.

I think it should. If action is required by me here (?) I will repost the commit for 4.4.

Hi Jon, yes, please do repost the commit. After reading through 
Documentation/networking/netdev-FAQ.txt, you probably want to send it 
with suitable subject-prefix so that the patch is not lost in the noise.

(Actually there is also a small change in the patch context.)

Ok. I'll do that. Just have to do proper testing first.
