From f122d33e4b0045a42238b9a4c3943adf7e8313c1 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Fri, 8 Feb 2013 15:15:11 +0200 Subject: usb: dwc3: core: explicitly setup and cleanup event buffers Make the call to dwc3_event_buffers_setup() and dwc3_event_buffers_cleanup() explicit, so it's easier to implement PM.
