Created a thread using alloc_ordered_workqueue() API in order to process
the works from firmware Work-queue sequentially instead of
create_singlethread_workqueue() API.
Changes in v1:
No need to check for backport compatibility in the upstream kernel.
so removing the else section where driver use
create_singlethread_workqueue() API if alloc_ordered_workqueue() API is
not defined, This else section is not required since in the latest upstream
kernel this alloc_ordered_workqueue() API is always defined.
Changes in v2:
Patch version change only.
