FAILED: patch "[PATCH] xhci: Don't let USB3 ports stuck in polling state prevent" failed to apply to 4.14-stable tree

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From d92f2c59cc2cbca6bfb2cc54882b58ba76b15fd4 Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Fri, 22 Mar 2019 17:50:17 +0200 Subject: [PATCH] xhci: Don't let USB3 ports stuck in polling state prevent suspend Commit 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect change or polling state is detected") was intended to prevent ports that were still link training from being forced to U3 suspend state mid enumeration. This solved enumeration issues for devices with slow link training. Turns out some devices are stuck in the link training/polling state, and thus that patch will prevent suspend completely for these devices. This is seen with USB3 card readers in some MacBooks. Instead of preventing suspend, give some time to complete the link training. On successful training the port will end up as connected and enabled. If port instead is stuck in link training the bus suspend will continue suspending after 360ms (10 * 36ms) timeout (tPollingLFPSTimeout).
