Subject: amd-xgbe: Use device workqueue instead of system workqueue
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afb43e8a0af18fa959e9ef09abfa969c3c83f4ef;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

amd-xgbe: Use device workqueue instead of system workqueue

The driver creates, flushes and destroys a device workqueue but queues
work to the system workqueue. Switch from using the system workqueue to
the device workqueue.
