Merge branch 'for-3.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue fix from Tejun Heo:
"This pull request contains a workqueue usage fix for firewire.
For quite a long time now, workqueue only treats two work items
identical iff both their addresses and callbacks match. This is to
avoid introducing false dependency through the work item being
recycled while being executed. This changes non-reentrancy guarantee
for the users of PREPARE[_DELAYED]_WORK() - if the function changes,
reentrancy isn't guaranteed against the previous instance. Firewire
depended on such nonreentrancy guarantee.
This is fixed by doing the work item multiplexing from firewire proper
while keeping the work function unchanged"

firewire: don't use PREPARE_DELAYED_WORK
