From cd12fd9f6d05d1b2b9ff2630802c55b5fd2e534c Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Fri, 7 Apr 2017 17:57:06 +0300 Subject: usb: xhci: remove enq_updates and deq_updates from ring enq_updates and deq_updates were introduced in the first place to check whether an xhci hardware is able to respond to trbs enqueued in the ring. We now have trb tracers to trace every single enqueue/dequeue trb. It's time to remove them and the associated debugging code.
