Subject: workqueue: check the allocation of system_unbound_wq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e5cba24e3f018d4beb6acd101a82483c98f91ce7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

workqueue: check the allocation of system_unbound_wq

I found a trivial bug on initialization of workqueue.
Current init_workqueues doesn't check the result of
allocation of system_unbound_wq, this should be checked
like other queues.
