by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled xhci: xhci debugfs device nodes weren't removed after device plugged out to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: xhci-xhci-debugfs-device-nodes-weren-t-removed-after-device-plugged-out.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 8c5a93ebf7ac56d47f879b3c7c2f8c83b40c2cdb Mon Sep 17 00:00:00 2001 From: Zhengjun Xing <zhengjun.xing(a)linux.intel.com> Date: Mon, 12 Feb 2018 14:24:50 +0200 Subject: xhci: xhci debugfs device nodes weren't removed after device plugged out From: Zhengjun Xing <zhengjun.xing(a)linux.intel.com> commit 8c5a93ebf7ac56d47f879b3c7c2f8c83b40c2cdb upstream. There is a bug after plugged out USB device, the device and its ep00 nodes are still kept, we need to remove the nodes in xhci_free_dev when USB device is plugged out.
