It already takes a file pointer. The inode associated with that had damn well better be the same one we're passing in anyway. Thus, there's no need for a separate argument here.
Also, get rid of the bogus check for a null pCifsInode pointer. The CIFS_I macro uses container_of(), and that will virtually never return a NULL pointer anyway.
