Change since v1:
[PATCH 3/4]: Rename link file's name "child" to "device", add check of
return value of
sysfs_create_link() and handle error properly.
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 d124a60dbb "USB: isp1760-if:
Change to use irq_of_parse_and_map" of usb-next tree
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
