usb: roles: fix a potential use after free

2019-12-17T18:55:46+00:00

commit 1848a543191ae32e558bb0a5974ae7c38ebd86fc upstream. Free the sw structure only after we are done using it. This patch just moves the put_device() down a bit to avoid the use after free.

Pull USB updates from Greg KH: "Here is the big set of USB patches for 5.4-rc1. Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things. The usual gadget and xhci and usb serial driver updates, along with a bunch of sysfs file cleanups due to the driver core changes to support that. Nothing really major, just constant forward progress.

usb: roles: get usb-role-switch from parent

2019-09-03T16:00:43+00:00

when the USB host controller is the parent of the connector, usually type-B, sometimes don't need the graph, so we should check whether it's parent registers usb-role-switch or not firstly, and get it if exists.

usb: roles: Add fwnode_usb_role_switch_get() function

2019-09-03T14:46:17+00:00

The fwnode_usb_role_switch_get() function is exactly the same as usb_role_switch_get(), except that it takes struct fwnode_handle as parameter instead of struct device.

usb: roles: intel: Enable static DRD mode for role switch

2019-09-03T13:56:36+00:00

Enable static DRD mode in Intel platforms which guarantees successful role switch all the time. This fixes issues like software role switch failure after cold boot and issue with role switch when USB 3.0 cable is used. But, do not enable static DRD mode for Cherrytrail devices which rely on firmware for role switch.

usb: roles: intel_xhci: Supplying software node for the role mux

2019-08-26T09:36:53+00:00

The primary purpose for this node will be to allow linking the users of the switch to it. The users will be for example USB Type-C connectors. By supplying a reference to this node in the software nodes representing the USB Type-C controllers or connectors, the drivers for those devices can access the switch.

Add a helper to match the firmware node handle of a device and provide wrappers for {bus/class/driver}_find_device() APIs to avoid proliferation of duplicate custom match functions. Cc: "David S.
