usb: hub: rename khubd to hub_wq in documentation and comments
USB hub has started to use a workqueue instead of kthread. Let's update the documentation and comments here and there. This patch mostly just replaces "khubd" with "hub_wq". There are only few exceptions where the whole sentence was updated. These more complicated changes can be found in the following files: Documentation/usb/hotplug.txt drivers/net/usb/usbnet.c drivers/usb/core/hcd.c drivers/usb/host/ohci-hcd.c drivers/usb/host/xhci.c Signed-off-by: Petr Mladek <pmladek@suse.cz> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
