USB: EHCI: Rearrange create_companion_file() to avoid GCC-4.6 warnings.
In create_companion_file() there is a bogus assignemt to i created for the express purpose of avoiding an ignored return value warning. With pre-release GCC-4.6, this causes a 'set but not used' warning. Kick the problem further down the road by just returning i. All the callers of create_companion_file() ignore its return value, so all is good: o No warnings are issued. o We still subvert the desires of the authors of device_create_file() by ignorning error conditions.
