Message-ID: <1457672269-29584-1-git-send-email-rajesh.bhagat@nxp.com> Date: Fri, 11 Mar 2016 10:27:49 +0530 From: Rajesh Bhagat <rajesh.bhagat@....com> To: <linux-usb@...r.kernel.org>, <linux-kernel@...r.kernel.org> CC: <mathias.nyman@...el.com>, <gregkh@...uxfoundation.org>, Rajesh Bhagat <rajesh.bhagat@....com> 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.
