From d4fc8bf59746b6ef9bdbec42a608b89d0221b7df Mon Sep 17 00:00:00 2001 From: Rajesh Bhagat Date: Fri, 11 Mar 2016 10:27:49 +0530 Subject: [PATCH] xhci: fix typo in babble endpoint handling comment The 0.95 xHCI spec says that non-control endpoints will be halted if a babble is detected on a transfer. The 0.96 xHCI spec says all types of endpoints will be halted when a babble is detected. Some hardware that claims to be 0.95 compliant halts the control endpoint anyway.
