From 1ba6108f5fc02f04784e7206ed08d10805035507 Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Thu, 1 Dec 2011 14:41:46 -0800 Subject: [PATCH] xhci: Remove debugging about ring structure allocation. Debuggers only really care what the xHCI driver sets the ring dequeue pointer to, so make the driver stop babbling about the memory addresses of internal ring structures. This makes wading through the output of allocating and freeing 256 stream rings much easier by reducing the number of output lines per ring from 9 to 1.
