commit e912e685f372ab62a2405a1acd923597f524e94a upstream. This phone needs to be handled by a specialised firmware tool and is reported to crash irrevocably if cdc-acm takes it. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

usb: dwc3: Fix assignment of EP transfer resources

2016-03-03T23:07:10+00:00

commit c450960187f45d4260db87c7dd4fc0bceb5565d8 upstream. The assignement of EP transfer resources was not handled properly in the dwc3 driver. Commit aebda6187181 ("usb: dwc3: Reset the transfer resource index on SET_INTERFACE") previously fixed one aspect of this where resources may be exhausted with multiple calls to SET_INTERFACE. However, it introduced an issue where composite devices with multiple interfaces can be assigned the same transfer resources for different endpoints. This patch solves both issues. The assignment of transfer resources cannot perfectly follow the data book due to the fact that the controller driver does not have all knowledge of the configuration in advance. It is given this information piecemeal by the composite gadget framework after every SET_CONFIGURATION and SET_INTERFACE. Trying to follow the databook programming model in this scenario can cause errors. For two reasons: 1) The databook says to do DEPSTARTCFG for every SET_CONFIGURATION and SET_INTERFACE (8.1.5). This is incorrect in the scenario of multiple interfaces. 2) The databook does not mention doing more DEPXFERCFG for new endpoint on alt setting (8.1.6). The following simplified method is used instead: All hardware endpoints can be assigned a transfer resource and this setting will stay persistent until either a core reset or hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and do DEPXFERCFG for every hardware endpoint as well. We are guaranteed that there are as many transfer resources as endpoints. This patch triggers off of the calling dwc3_gadget_start_config() for EP0-out, which always happens first, and which should only happen in one of the above conditions.

xhci: Fix list corruption in urb dequeue at host removal

2016-02-25T20:01:22+00:00

commit 5c82171167adb8e4ac77b91a42cd49fb211a81a0 upstream. xhci driver frees data for all devices, both usb2 and and usb3 the first time usb_remove_hcd() is called, including td_list and and xhci_ring structures. When usb_remove_hcd() is called a second time for the second xhci bus it will try to dequeue all pending urbs, and touches td_list which is already freed for that endpoint.

Revert "xhci: don't finish a TD if we get a short-transfer event mid TD"

2016-02-25T20:01:22+00:00

commit a6835090716a85f2297668ba593bd00e1051e662 upstream. This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") Turns out that most host controllers do not follow the xHCI specs and never send the second event for the last TRB in the TD if there was a short event mid-TD. Returning the URB directly after the first short-transfer event is far better than never returning the URB. (class drivers usually timeout after 30sec). For the hosts that do send the second event we will go back to treating it as misplaced event and print an error message for it. The origial patch was sent to stable kernels and needs to be reverted from there as well Signed-off-by: Mathias Nyman Signed-off-by: Greg Kroah-Hartman

usb: xhci: handle both SSIC ports in PME stuck quirk

2016-02-17T20:31:01+00:00

commit fa89537783cb442263fa5a14df6c7693eaf32f11 upstream. Commit abce329c27b3 ("xhci: Workaround to get D3 working in Intel xHCI") adds a workaround for a limitation of PME storm caused by SSIC port in some Intel SoCs. This commit only handled one SSIC port, while there are actually two SSIC ports in the chips. This patch handles both SSIC ports. Without this fix, users still see PME storm.

usb: phy: msm: fix error handling in probe.

2016-02-17T20:31:01+00:00

commit a38a08dfaaab978dced63aa9cad45f0f62e23a66 upstream. This driver registers for extcon events as part of its probe, but never unregisters them in case of error in the probe path. There were multiple issues noticed due to this missing error handling. One of them is random crashes if the regulators are not ready yet by the time probe is invoked. Ivan's previous attempt [1] to fix this issue, did not really address all the failure cases like regualtor/get_irq failures.
