    usb: storage: Add usb_stor_dbg, reduce object size · 75b9130e
    Joe Perches authored
    Reduce the size of the objects by consolidating
    the duplicated USB_STORAGE into a single function.
    
    Add function usb_stor_dbg to emit debugging messages.
    Always validate the format and arguments.
    Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG.
    
    Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG
    is set.
