Change since v3
[PATCH 3] Add check of udev->parent before define "struct usb_port
*port_dev" since if udev->parent is NULL, it would crash.
This patchset is to set DeviceRemovable according ACPI information
and create a new attribute "connect_type" under port device to expose
port connect type to user space. Patch3 create two link files under
port device and its child device to show their relationship under sysfs.
Following patchset is based on the commit f7b1b18 "USB: EHCI: fix build
error in ChipIdea host driver"
USB: Set usb port's DeviceRemovable according acpi information in EHCI
usb/xhci: set root hub's DeviceRemovable according to usb port connect type
usb: Create link files between child device and usb port device.
usb: Add "portX/connect_type" attribute to expose usb port's connect type
