Subject: usb: dwc2: Remove deprecated create_singlethread_workqueue
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ec7b1268510908157d4e8878bb753ea844446856;p=deliverable%2Flinux.git

usb: dwc2: Remove deprecated create_singlethread_workqueue

alloc_ordered_workqueue replaces the deprecated
create_singlethread_workqueue.

There are multiple work items on the work queue, which require
ordering. Hence, an ordered workqueue has been used.

The workqueue "wq_otg" is not being used on a memory reclaim path.
Hence, WQ_MEM_RECLAIM has not been set.
