    ide-{floppy,tape}: fix padding for PIO transfers · d93bc452
    Bartlomiej Zolnierkiewicz authored
    * Return number of bytes left to transfer from idetape_{in,out}put_buffers()
      and number of bytes done from ide_tape_io_buffers().
    
    * Fix padding for PIO transfers in ide_pc_intr() so read/write buffers are
      always completely processed and then the transfer is padded if necessary.
    
    * Remove invalid error messages.
    
    * Remove now superfluous padding from ide{_io_buffers,tape_input_buffers}().
    
    While at it:
    
    * Set pc->bh to NULL in idetape_input_buffers() after all bh-s are done.
    
    * Cache !!(pc->flags & PC_FLAG_WRITING) in local variable in ide_pc_intr().
