Subject: unisys: replace kthread_create and wake_up_process with kthread_run
X-Git-Tag: firefly_0821_release~176^2~1998^2~138^2~858
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=31c9b9cf40f8f03f6a7484f2c06c5eb31b3735ce;p=firefly-linux-kernel-4.4.55.git

unisys: replace kthread_create and wake_up_process with kthread_run

kthread_run calls kthread_create and if the thread is created
it then calls wake_up_process on the corresponding returned
task struct. So the code can be simplified by calling just
kthread_run.
