It is a Linux PATCH and Linux uses TABS for indent.
I then check other patches I had I my Inbox and they were the same, no TABs

webkit-gtk-2.28.4

I can forward the patch I tried:

commit 2fb541c862c9 ("net: sch_generic: aviod concurrent reset and enqueue op 
for lockless qdisc")

When the above upstream commit is backported to stable kernel,
one assignment is missing, which causes two problems reported
by Joakim and Vishwanath, see [1] and [2].

So add the assignment back to fix it.
