Subject: [PATCH 3/3] phy: sun4i-usb: Use power efficient workqueue for debounce and poll
From: Yangtao Li <frank@...winnertech.com>
The debounce and poll time is generally quite long and the work not
performance critical so allow the scheduler to run the work anywhere
rather than in the normal per-CPU workqueue.
