[PATCH] workqueue: Remove redundant call for pwq_adjust_max_active

From: Libin
Date: Sun Dec 08 2013 - 22:32:31 EST


From: Li Bin <huawei.libin@xxxxxxxxxx>

In __alloc_workqueue_key(), alloc_and_link_pwqs() already called
pwq_adjust_max_active() to update the pwq's max_active, but after
that there is a redundant call for pwq_adjust_max_active. It is
meanless, remove it.
