Alan Stern 9da82bd464 USB: implement "soft" unbinding ... This patch (as1091) changes the way usbcore handles interface unbinding. If the interface's driver supports "soft" unbinding (a new flag in the driver structure) then in-flight URBs are not cancelled and endpoints are not disabled. Instead the driver is allowed to continue communicating with the device (although of course it should stop before its disconnect routine returns). The purpose of this change is to allow drivers to do a clean shutdown when they get unbound from a device that is still plugged in. Killing all the URBs and disabling the endpoints before calling the driver's disconnect method doesn't give the driver any control over what happens, and it can leave devices in indeterminate states. For example, when usb-storage unbinds it doesn't want to stop while in the middle of transmitting a SCSI command. The soft_unbind flag is added because in the past, a number of drivers have experienced problems related to ongoing I/O after their disconnect routine returned. Hence "soft" unbinding is made available only to drivers that claim to support it. The patch also replaces "interface_to_usbdev(intf)" with "udev" in a couple of places, a minor simplification.
