Subject: PM / Runtime: Use alloc_workqueue() for creating the PM workqueue
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bcb5ba8b4e8a5ae14b27351bdf499dd4c3bcc944;p=openwrt%2Fstaging%2Fblogic.git

PM / Runtime: Use alloc_workqueue() for creating the PM workqueue

Although we need the PM workqueue to be freezable, we don't need it
to be singlethread.  Also, the number of concurrent work items
running on a single CPU need not be constrained.  For these reasons
use alloc_workqueue() directly, with suitable arguments, instead of
create_freezeable_workqueue(), to create the runtime PM workqueue.
