USB: Add udev argument to interface suspend/resume functions
This patch (as1127) makes a minor change to the prototypes of the usb_suspend_interface() and usb_resume_interface() routines. Now the usb_device structure is passed as an argument, instead of being computed on-the-fly from the usb_interface argument. It makes the code look simpler, even if it really isn't much different from before. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
