patch "xhci: Add missing CAS workaround for Intel Sunrise Point xHCI" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled xhci: Add missing CAS workaround for Intel Sunrise Point xHCI to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From ffe84e01bb1b38c7eb9c6b6da127a6c136d251df Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Mon, 1 Oct 2018 18:36:07 +0300 Subject: xhci: Add missing CAS workaround for Intel Sunrise Point xHCI The workaround for missing CAS bit is also needed for xHC on Intel sunrisepoint PCH.

Unfortunately a previous refactor removed the code freeing the buffers because it looked extremely similar to the code killing the URBs. As a result, there were many new leaks for each plug/unplug cycle of a CDC-ACM device, that were detected by kmemleak. Restore the missing code, and the memory leak is removed.

patch "USB: serial: simple: add Motorola Tetra MTP6550 id" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: simple: add Motorola Tetra MTP6550 id to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From f5fad711c06e652f90f581fc7c2caee327c33d31 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Mon, 24 Sep 2018 15:28:10 +0200 Subject: USB: serial: simple: add Motorola Tetra MTP6550 id Add device-id for the Motorola Tetra radio MTP6550.

patch "USB: serial: option: improve Quectel EP06 detection" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: option: improve Quectel EP06 detection to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 36cae568404a298a19a6e8a3f18641075d4cab04 Mon Sep 17 00:00:00 2001 From: Kristian Evensen <kristian.evensen(a)gmail.com> Date: Thu, 13 Sep 2018 11:21:49 +0200 Subject: USB: serial: option: improve Quectel EP06 detection The Quectel EP06 (and EM06/EG06) LTE modem supports updating the USB configuration, without the VID/PID or configuration number changing. When the configuration is updated and interfaces are added/removed, the interface numbers are updated. This causes our current code for matching EP06 not to work as intended, as the assumption about reserved interfaces no longer holds. If for example the diagnostic (first) interface is removed, option will (try to) bind to the QMI interface. This patch improves EP06 detection by replacing the current match with two matches, and those matches check class, subclass and protocol as well as VID and PID. The diag interface exports class, subclass and protocol as 0xff. For the other serial interfaces, class is 0xff and subclass and protocol are both 0x0. The modem can export the following devices and always in this order: diag, nmea, at, ppp. qmi and adb. This means that diag can only ever be interface 0, and interface numbers 1-5 should be marked as reserved. The three other serial devices can have interface numbers 0-3, but I have not marked any interfaces as reserved. The reason is that the serial devices are the only interfaces exported by the device where subclass and protocol is 0x0. QMI exports the same class, subclass and protocol values as the diag interface. However, the two interfaces have different number of endpoints, QMI has three and diag two. I have added a check for number of interfaces if VID/PID matches the EP06, and we ignore the device if number of interfaces equals three (and subclass is set).
